How are you supposed to refill the engines then? I tried doing it from a fire hydrant, but it wasn't letting me connect a hose to it to refill the engine.
EDIT: Was able to find the manual and you have to hold down left shift to connect to hydrant/tender.
Additionally, found the police dog and doctor kits are still written in German.
Also, found an untextured house and barn, see below:
