Lionel O27 tinplate track

Check for updates

Lionel tinplate track in O-27 profile is a very popular choice for smaller O-gauge layouts. The O27 series track dates from 1930s. The principal difference between the O27 and the regular O track is the diameter of the smalles curve: nominally 27 inches for O27 and 31 inches for regular O (in reality about 30 inches across the outside rails). 

Track components in this style have been produced by a number of manufacturers, withe Lionel, K-Line and Marx represented in the RR-Track O27 library. Tinplate track and components such as switches have the advantage that they are ready to go out of the box; very little or no additional assembly or wiring is required to assemble a layout.

The current v5 build number for the Lionel/K-Line/Marx O27 library is 4.60.010. If yours is earlier than this, go to our updates page to download and install the current version.

This track library contains a wizard for track laying automation.
