Forgive my poor English

interesting,i think thats because usually,for railroads,locomotive are dependent unit,unlike multiple units which are using as a whole,one or a pair locomotive can be used to draw several train,which require to be easy to mobilize，obviously,a-b-b-a is easier than a-b+b-a to mobilize.

no idea honestly. i could guess that it had to do with the observation cars, but i honestly have no clue

Out of curiosity, do you know why railroads chose the A-B-B-A configuration instead of having A-B at the front and B-A at the back of the train? Surely it would have saved time as the locomotives wouldn't have to be moved to the other end of the train. It would also have looked gorgeous, like a mid-century HST.

Oh yeah no, most of the time I'm fine with people using them as long as it's not for payware. Don't want people profiting of my literal 1000s of hours. Lol

Oh cool! I was about to go on a spiel about how I fully understand your right to protect your IP, but now there's no need.

No people definitely can reskin them! I know tissues is planning GN, and santadino has a few more. Interns mod was broken though. I've been working with him on it, but he removed the skirts on all his models and uploaded the teasers textures as well, his mod was almost 1gb where it should have been no more than 75mb. He'll be uploading a fix soon

I'm curious, someone recently released a streamlined coach set based on your models for the Santa Fe Superchief. But then they removed their mod a day or so later. Do you prohibit other modders from creating skins for your mods?

Ooh I can fix that

The fantasy pullman ob car,its rear light dislocated when camera far from it，guess its a bug to be fixed
