When trying to drive the 3F reverser wont move leaving me stuck I'm unsure if this is a bug or I'm doing something wrong
No bug... user error. Read page 6 of the manual it explains in detail how to unlock & operate the reverser. This is a complex Pro-Line product, you should always study the manual for any of these locos before trying to drive them. You can easily access the manuals for any Steam product from the store page. e.g. https://store.steampowered.com/app/222575/Train_Simulator_LMS_Class_3F_Jinty_Loco_AddOn/
