Here is my Version of Chessie B&O SD40-2 in Searchlight Simulations using the Conrail version. (I downloaded the RAR file from Dropbox to my laptop to ensure that I had deleted all the geo files.) You can download from the Dropbox link below if you want to try it out. You will need to delete my previous CP beaver model CPB as I recycled it into this version. I will have CP Beaver and Pacman versions out soon to replace it. Let me know what you think.

You need to copy the geo files from the searchlight Conrail model as shown in blue below. Drop the corresponding geos in straight into the engine and cab folders. For the lights casting and lights non casting You need to put the geos in the headlight folders

I also did a blue version of the B&O that could use some Pro repainter TLC. LOL
