Hi Devs, The scenarios suggest to make sure on especially the Ruhr-Sieg Nord line after finishing the shift and shutting down the locomotive or at least power it down to make sure it's locked up and secure. Ironically you can't technically do that because there's no key to lock the doors up. So my wish here as funny as it sounds, we need a key to lock up the locomotive. Idealy you want to see the whole animation and key beeing put into the keyhole and twisting it to lock or unlock the door. You'd have to probably do this for all doors round the locomotive on the outside, try to work something out.
