what he means is locomotives, rolling stock ect. I have the same problem. i downloaded a locomotive (kuid 94769100092) extracted it with content dispatcher, and checked it with content manager to see if it was there. I then launched trs2004 and went to railyard to see if it was there. the name showed up but the preview was blank. I also went to my route and aded the loco, but nothing happened when i clicked add and the direction arrows were not there. CAN SOMEBODY PLEASE HELP ME???
