I have completed the bulk of the driving van trailor excluding some minor details for my IC 225 set. These trains operate in push pull formation with a driving trailor often at the front of the train with the locomotive at the back. These trains are some of the fastest to use this system operating at 125mph and once achieving 161 mph with the locomotive at the rear on a test train. submitted by /u/Cptbillbeard [link] [comments]
