Wait were the MOM trains broken? Because I remember using them on the latest version of MOM and they seemed to work fine.

Ah, I understand.

MOM team said previously that their mod should work only with vanilla game and nothing else. So I removed MOM compatible trains from workshop until they solve their internal issues and realize that Steam Workshop is not made for one mod.

I'm assuming it'll be sorted out eventually, if not it's not a big deal I have other plans to handle the situation.

If you want context you can check Railway Replacer (or collection) I explained it better there.

Why were the metro versions of the Siemens and Bombardier train sets removed?

Any plans to introduce more metro trains for the Metro Overhaul Mod? (i.e. MPM-10 (Montreal))
