Converting Bachmann On30 cars to O or O27?

There’s always a discussion about the cost of O gauge/O scale somewhere, mostly because it’s hard to find new locomotives for less than $500 and new train cars for under $75. You’d think this was a hobby for trial lawyers and brain surgeons.

One guy pointed out how much bang for the buck he’s getting when he buys On30.

Now, a bit of terminology here. O scale is 1:48 scale. One quarter inch on the model is equal to a foot on the real-world equivalent. O27, the cheaper brother of O scale, is actually 1:64 scale, though it runs on the same track. “Serious” hobbyists often look down on O27, but the nice thing about O27 is it lets you pack a lot more into a smaller space.

So what’s this On30 stuff and what’s the difference between it and regular O or O27 scale?

I’m glad you asked.

On30, On3, and the like refer to “narrow gauge.” Most train track in the United States has its rails 4 feet 8 inches (or 8 1/2 inches) apart. That’s “Standard gauge.” Occasionally, a railroad would lay its track 3 feet apart, or 30 inches apart, or some other measurement narrower than 4’8.5″. This was especially common out west in regions where they had to deal with a lot of mountains. On30 refers to 1:48 scale models of 30-inch gauge trains. On3 refers to 1:48 scale models of 3-foot gauge trains. On2 refers to 1:48 scale models of 2-foot gauge trains. And so on. I’ve talked more about On30 here if you want to know more.

Now it just so happens that the distance between the rails on regular old HO scale track measures out to 31.3 inches in O scale. For most people, that’s certainly close enough. O scalers have been living with track that’s 5 scale feet wide ever since we decided that O scale was 1:48, back in the 1930s or so.

So Bachmann, the makers of the cheap HO and N scale train sets you see in big box stores, decided to take advantage of this convenient accident, make some 1:48 scale cars, put narrow trucks on them, bundle some HO scale track and commercialize On30. So now it’s actually easier in some regions to get a Bachmann On30 train set than it is to get a Lionel O train set.

I found this page on converting Bachmann On30 cars to S scale. What the author did was remove the Bachmann trucks and couplers and substitute American Flyers. Since S scale stuff is even more scarce than regular O scale, this is a slick trick. And, as you can see from the pictures, for the most part the stuff still looks right. Rivet counters won’t like it, but if you’re a rivet counter you’re probably not reading this page anyway. For people starved for inexpensive trains, or for trains, period, they’re fine.

Well, I like my Lionels. I’m not going to convert to On30. But I don’t like Lionel prices. So I build some of my own stuff, and the stuff I do buy, I buy used. So I’ve amassed a pretty sizeable collection, even though I’ve spent a lot less than most hobbyists will spend on a single locomotive.

But I’m always looking for something new and different.

A K-Line passenger car costs $117. A Bachmann passenger car costs $28.

A pair of K-Line freight trucks costs $8. Are you thinking what I’m thinking?

You can’t put freight trucks on a passenger car. That’s what I’m thinking. Freight trucks are different from passenger trucks for some reason. Something about people wanting a smoother ride than cows.

But you get the idea. $36 is a lot less than $117.

K-Line passenger trucks are $25 apiece. That’s more than the car. But $78 is still less than $117, though I’d just live with using freight trucks, myself.

If the S scalers can do it, why can’t we?

What day is it again?

Passing a few minutes before a movie started tonight, my girlfriend and I went into a nearby store to look around. And what did we find?

Christmas stuff.

Am I smoking crack, or is it still August?I probably shouldn’t encourage them, but I bought some stuff. Many of those collectible holiday village sets happen to be sized about right for O scale Lionel trains. Those that aren’t are usually sized about right for HO scale. I doubt it’s an accident. Around 100 years ago, J. Lionel Cowen convinced everyone that a train belonged around the Christmas tree. These days, ceramic villages and figures are more popular than the trains, and the big brands are every bit as overpriced as anything Lionel or MTH have made in the past decade, but they’re still sized so they’ll look right if a Lionel train escapes from the attic and ventures into the neighborhood. New traditions have a better chance of usurping older traditions if they fit in with them first.

These weren’t Lemax or Department 56. They were cheap knockoffs. This particular series of knockoffs pairs up O scale-sized figures with HO scale-sized buildings. Not my thang. I’m anything but a scale bigot but half-sized buildings get on my nerves.

But I bought a few figures. They came four to a package for a dollar. You’re lucky to pay less than $4 per figure at a hobby shop. For my four bucks, I got 16 figures.

Yes, the figures are dressed in heavy coats and there’s snow on the bases they stand on. So I won’t have them on the train layout at the same time as my open-top convertible 1:43-scale cars. But the availability of the figures makes it just as cheap and easy to make winter scenes, just like the 50-cent Homies figures make it cheap and easy to make summertime scenes.

Useless trivia answer: If you’ve ever wondered where 1:43 scale toy cars come from, they come from trains as well. The British decided that O scale should be 1:43, and Hornby decided it would be nice to be able to sell cars with which boys could populate their cities. The cars became popular toys in their own right, and the 1:43 scale was copied by other companies, so 1:43 scale cars lived on long after Hornby stopped selling O scale trains.

End useless trivia.

Where was I? Oh yeah. Useless Christmas merchandising in August. I decided I wanted 16 vaguely O scale figures in winter dress more than I wanted $4.24.

But I passed on the wreaths and the holly. I can’t think of any good use for those in my basement.

I was on vacation

I went on vacation and I guess my DSL connection got jealous. As far as I can tell it died two days into the trip. Figures. So that’s why the site’s been dead.

If it interests youm I’ll tell you about my trip.I went with the girlfriend’s family to Orange Beach, Alabama, which is close to Pensacola, Florida. In Alabama the beaches are just about as white and much easier to walk on because it’s softer, but the shell hunting is better across the Florida border.

My St. Louis buddies say I’ve already lost the twang I picked up down there. That’s a good thing. I’m a northern boy.

Train fans will have something to look at near the intersection of highways 59 and 98 in Foley, AL. An old Louisville & Nashville diesel switcher locomotive, L&N caboose and boxcar are there, along with a St. Louis-San Francisco (Frisco) boxcar. They appear to be in reasonably good condition.

The Naval Aviation Museum in Pensacola is excellent. I could spend days there. Take the 11 AM restoration tour if at all possible. They take you out into the airfield where planes that won’t fit in the museum are displayed, but they also take you inside the hangar where you can see their works in progress. In front of the hanger was what was left of a Brewster Buffalo, an early Navy fighter from World War II. It’s something of a holy grail today, because its ineffectiveness against the Japanese Zero doomed it early in the war. We sold a bunch of them to Finland and palmed a few more off on the British while the Navy did its best with the Grumman Wildcat, which was slightly less ineffective, while waiting for the Hellcat and Corsair fighters.

But anyway, they had the *censored*pit section of a Buffalo in front of the hangar and another Buffalo inside, which was waiting for its wings to be installed and a trip to the paint shop. They were also working on a replica of Amelia Earhart’s Lockheed Electra. She wasn’t in the Navy, but her role in aviation and women’s acceptance in it means the museum was interested in the plane. The widespread belief that the Japanese believed her to be a U.S. spy and shot her plane down doesn’t hurt, either.

For great fish and seafood, check out Original Oyster House in Gulf Shores, AL. We had an hour and a half wait, which we passed by browsing the adjacent shops. I imagine that’s the source of most of those shops’ business. The shops aren’t earth-shattering but won’t bore you to tears either. The seafood is.

Flounders Chowder House in Pensacola Beach, Florida, is also amazing. Don’t ask me which one’s better. I think Flounders has the better atmosphere but the food in both places is first-rate. While just about every seafood place in the area is going to be better than Red Lobster, it’s easy to find disappointingly mediocre seafood in the area. But these two places knocked my socks off.

I made a new friend outside Papa Rocco’s in Gulf Shores. A sign outside Papa Rocco’s advertises warm beer and lousy pizza. Seriously, that’s what it said. I was walking across the Papa Rocco’s lot on my way to a souvenir shop when a woman started yelling at me. I kept walking but turned a couple of times. When I turned and looked at her, she yelled, "Yeah, I’m talking to you!" She wasn’t anyone I knew and she was obviously drunk. I have no idea why she was upset with me. I picked up my pace and got lost in the souvenir shop as quickly as I could.

I was crossing Papa Rocco’s to get a good look at Tracks To BBQ. Obviously if I’m on the Atlantic coast I’m going to eat seafood, since I can get good BBQ closer to home. But the ad for Tracks To advertised "Antique model train cars on display." So of course I wanted to check it out. Peering into the window, I was able to see that it was a small establishment, with only two or three tables inside. I saw a couple of Lionel posters on the wall and some assorted trinkets in the window. Further back, next to the cash register, I saw a couple of old OO or HO scale train cars that looked pretty old. What appeared to be a locomotive in the original box sat next to them. On a shelf below that I saw a postwar Lionel hopper car. I paid $10 for the same car at a swap meet last month. Nothing earth shattering there, at least not from what I could see inside. That’s not to say there wasn’t something cool running on a shelf under the ceiling, but I couldn’t tell from outside and the establishment was closed.

I’d hoped to see some prewar tinplate. Oh well.

The outlet mall in Foley is large and you can spot the occasional bargain. Some of the shops were handing out 40% off coupons for other shops in the complex. I got a pair of $50 Reebok tennis shoes for $20. I thought about buying a pair of the canvas Reebok Classic shoes as well. They would have been $12 with a coupon. I’ve had a couple of pairs of them in the past and they’re decent shoes. I’ve had shoes that were better looking and lasted longer, but in most cases I also paid $60 for them.

But as with all of these kinds of places, caveat emptor. I tried on plenty of shoes with lumpy soles. Those shoes aren’t worth taking for free because of what they’ll do to your feet. And mixed with the bargains you can find some high-priced items that are trading on reputation. Careful shoppers can save a bundle though.

I also learned that a large sand castle can attract a lot of attention. We built one large enough for a 4-year-old to hide in completely. It drew lots of looks and comments.

A model railroad scale conversion chart

Plans in model railroad books and magazines are often in a different scale from your favorite. Having a model railroad scale conversion chart helps.

I’m into O scale and the rest of the world, it usually seems, is not. Dimensions for published plans are almost always sized to HO scale, or even S scale of all things. Of course, after A. C. Gilbert imploded in 1967 and took American Flyer with it, it seemed like the “S” is S scale stood for “scratchbuild,” because building it yourself was the only way you were going to get anything, so I guess that’s fair.

Here’s a cheatsheet you can use to convert measurements from one scale to another.

Assumptions: O scale is 1:48, G scale is 1:22.5. If you use a different measurement for either scale, I’m sorry. This won’t be much use to you.

G Scale O ScaleS ScaleOO ScaleHO ScaleTT ScaleN ScaleZ Scale
G Scale213%284%339%386%533%711%977%
O Scale47%133%158%181%250%333%458%
S Scale35%75%119%136%188%211%289%
OO Scale30%63%84%115%158%211%289%
HO Scale26%55%73%87%138%184%253%
TT Scale19%40%53%63%73%133%183%
N Scale14%30%40%48%54%75%138%
Z Scale10%22%29%35%40%55%73%

Find your scale in the table along the top. Then scroll down to the desired scale and find out the factor you need to enlarge or reduce. So, if, say, I have HO scale plans I want to enlarge to O scale, I run across the top to HO, then down to O scale, and see that I need to enlarge the plans to 181%. If I have O scale plans I want to reduce to S scale, I run across the top to O and down to S, and see I need to reduce the plans to 75%.

You can also do this if a building you want exists in kit form for a different scale. Measure it. Then do the math based on the chart to figure out what size to build everything for your scale of choice.

On a somewhat related note, if you’re unsure what scale something is, here’s how to figure that out before you convert it. You might also find my cross-hobby scale conversion helpful.

I need to build this in O gauge

I visited the site because the link promised billboards. I got so much more. Now the fine Scot in me really wants to build this box car.

Since my trains are O27, not HO, I can’t use his artwork directly. But his HO scale decals might be suitable for a tinplate 6-inch car like those American Flyer and Marx used to sell, since those 6-inch Marxes basically look like double-height HO cars.This is precisely why I’m not a rivet-counter. Trains are supposed to be fun. This car doesn’t exist in the real world, but it’s fun. The Second Amendment Gun Shop with a sign in the window saying “No weapons allowed” doesn’t exist in the real world, but it’s fun.

I try to keep elements of what I do believable–you won’t see any low-rider Honda Civics running around my layout, which is supposed to look like the 1950s because my trains were built in the ’50s–but since I can’t build models of a specific time and place, what’s the point of getting uptight about whether M-K-T box car 45001 really existed?

But hey. For some people that’s the best part of the hobby. That’s OK. Just don’t try to stop me from having my fun.

A more permanent home for Dad’s Lionel

Gatermann and I spent the afternoon building a train table. I started building one about a month ago but got too busy to finish it. Today was the day I’d set aside to get some work done on it.
