Integrated roadbed track sections, tracks with an added plastic base designed to look like ballasted roadbed, are often packaged in train sets and marketed toward beginners. Don’t let the stigma fool you into thinking they have no place on a permanent layout. Integrated track sections do have some limitations; plans are limited to the pieces available, and cutting tracks to fit special circumstances can be a challenge.
However, all tracks share the same rail joiners and can be interchanged with some modifications to the roadbed sections. Combining integrated roadbed sections and standard sections or flexible track pieces can give you the flexibility of the latter without having to give up the investment you’ve already made in track.
Although the integrated roadbeds of different manufacturers are all slightly different, the simple steps shown here should work for all. The tracks shown here are HO scale Code 83 products from Atlas. Atlas’ integrated roadbed tracks are designed for the easy compatibility with their standard product lines. The roadbed is actually a separate piece that can be removed all together.
Lay out your track plan as you would normally. Use a cork or foam roadbed beneath standard track pieces to match the height of the integrated roadbed tracks. For the Atlas sections used here, the heights match nearly perfectly. Other manufacturer’s tracks may have a slightly higher profile. If necessary, shim the standard track to the proper height with plastic strips to get a smooth transition.
Most manufacturer’s roadbed sections have plastic clips at each end designed to lock the tracks together. Use a small razor saw to trim off the clip at the transition joint. Now the two sections can be joined using the metal rail joiners like any other tracks. Secure the standard track section with track nails.
A coating of ballast over both pieces and you’ll never know where the “train set” ends and the “serious” track begins!
