What is Delrin?

Perhaps the most lasting legacy of Model Products Corporation on the history of Lionel trains was its use of a material called Delrin. And their competitors, including Marx and K-Line, quickly started using it too. But what is Delrin, and why was it better than the tried and true stuff Lionel Corporation used?

Delrin is a trademark of DuPont, a type of plastic called Polyoxymethylene POM. You can cast parts from it like other plastics such as styrene or ABS, but it is slippery and self-lubricating.

Lionel 115 station

The Lionel 115 station is a popular centerpiece for pre-war tinplate layouts. While best suited for standard gauge trains, its design does lend itself to o gauge, and it was one of Lionel’s pre-war designs that went back into production during the post-war era. Its first run lasted from 1935 to 1942, with a revival from 1946 to 1949.

The Lionel 115 is the second largest station Lionel produced, second only to the 116 station, which has a similar appearance. Its design was inspired by New York city’s Grand Central station, but it used selective compression to give the impression of a big city station without taking the space that would be required of a true scale model.
