This is version 2 of my previous railcar float that you can make to almost any size you want. Most of the deck details have been removed and are printed separately now. They can be omitted or painted then glued to the model for easy painting. Deck height is 10mm. Track centers are 1 1/4 inches or 32mm apart.

Updates to v2:

-Tracks are now the standard 1 1/4 inches or 32mm center to center.
-Rail spikes are now strips so they can be reprinted if damaged inserting a rail.
-With most deck details removed the "Ironing" feature on slicers can be used easier for a smoother deck.
-Several minor fixes and designing measurements.
