“Super utility” tinplate train cars

Dave Farquhar Toy trains , , , , , , ,

Tin train cars had a variety of methods to couple them together, but by far the most common method was a coupler commonly called tab-in-slot. The tab from one car mated with a slot in the next. All of the train manufacturers used a variant of this method at one point or another, and all of them would be able to couple together, if not for one nagging detail: height.

Repair a Marx reverse unit

When it comes to Marx repairs, the reverse unit is the end of the innocence. Motor repairs are rather easy; reverse unit repair can be as hard as you want it to be.

I’ll share some things I do that seem to make it easier to service a Marx reverse unit.

Fix a seized Lionel motor

Dave Farquhar Toy trains

I got a 4-wheel Lionel motor over the weekend. It was seized up to the point that the wheels wouldn’t turn, which meant I got it for almost nothing. The fix isn’t always this easy, but it’s common enough to be worth taking a chance on these neglected motors.

The low-effort fix for a Marx motor

I had a Marx motor that wouldn’t run, and I fixed it with almost no effort. If you need to get a Marx motor running again but can’t put a lot of time and effort into it, I’ve developed a quick fix. It’s only temporary, but if you want to run trains today instead of fixing them, it can get you out of a pinch.

You need a screwdriver and one drop of Rail-Zip.

How to install American Flyer track locks

To held tracks hold together without nailing them down permanently, AC Gilbert marketed its #694 track locks. Sometimes people also call these track clips. The locks are u-shaped pieces of tin that came in a brown envelope with instructions on the front. If you’ve lost the instructions, or bought the clips secondhand and never got them, here’s how to install American Flyer track locks.

These track locks are indispensable for setting up a layout on the floor.

Replace the plug on a Lionel transformer

Dave Farquhar Toy trains ,

Lionel transformers were built to last. Perhaps the most frequent issue with them is a messed-up power cord. But sometimes the cord is OK but it needs a new plug.

Replacing a power cord is easier than it sounds, but replacing just the plug is easier still.

Repairing Marx one-way couplers

Repairing Marx one-way couplers

Marx one-way couplers were an effort to provide trains that could automatically couple and uncouple. The design was exceptionally reliable, as long as the trains were carefully stored after use. It’s not uncommon today to find them in inoperable condition, but it’s possible to repair them.

Prior to World War II, every train manufacturer tried different ways to make trains that could automatically couple and uncouple, with varying degrees of success. None were particularly realistic, and Marx’s design was probably the ugliest, but did I mention it worked really well?

A reverse lockout switch for Marx trains

Dave Farquhar Toy trains , ,

The only thing I don’t like about Marx trains is that most of them don’t have a switch to lock the locomotive in one direction. Fortunately it’s not hard to add a reverse lockout switch for Marx if you don’t want to do a temporary lockout.

It’s a cheap project–all you need is about a foot of wire, a toggle switch, some heat shrink tubing (1/4 inch or smaller) or electrical tape, and your soldering iron.

Simple tips to prevent ransomware

Dave Farquhar security , , , , , , , , ,

Last week at work, I noticed some odd events in an event log, and when I investigated them, I found they were part of a failed ransomware attack. This got me thinking about how to prevent ransomware at home.

Ransomware, if you aren’t familiar, is an attack that encrypts your data and demands a ransom, usually around $300, in bitcoins, and you get a short deadline until it destroys your files. More often than not, paying the ransom is the only way to get the files back, so it’s much better to prevent it.

Wire a Lionel motor without an e-unit

Sometimes you may want to remove an e-unit from a Lionel locomotive and rewire it to run in forward only, whether as a temporary measure while you repair the e-unit, or as a permanent modification.

It only requires a few splices to get the job done.
