These are Erie RR. repaints of G-Trax freeware lightweight streamlined passenger cars by Joe (XDriver) Nageotte.

Installation:
1- Extract the XDriver_Erie_Lgwt.rwp file in a temporary location.
2- Do one of these two steps:
 a) Start the TS Utilities program, choose "Package manager" then "Install", then choose the rwp file; OR
 b) Open the rwp file with 7zip and drag the "Assets" folder in your "Railworks" folder.

Rick Grout of G-Trax was kind enough to donate the lwt pack to the public domain, so the GeoPcDx files are included in this package.

These cars should be used with XDriver's Erie passenger F7 repaints available here in the RWA library
(search for "Erie RR F7A/B Units & Bonus ES44 Erie NS Heritage").
