I have downloaded all the required stock including the pay locos. The activities that I create are moving slowly, then freezes, then move slowly. Sometimes when I begin to run an act I get this Message: cant find RDCEng.sms. I downloaded the Budd zip file from TS. I tried to get the Budd RDC from ViaRail but cant. Am using AG4 for the FBL3 Temp. Thanks!

Sounds to me like this is a problem with rolling stock, or with a low power PC. What are the specs on your machine? Are you running the latest stable bin patch?

Have you checked all of your rolling stock with R-R and CB? Have you checked the FBL template activity file with R-R? If you still have rolling stock issues, R-R will spot them directly. You can then use AM to substitute stock which you do have, or CB to fix stock which might have a problem.
