It looks like FD is using the format xxxyz
xxx- station number
y- same as in the wiki (1=engine, etc)
z- same as wiki (0=mobile, etc)
And ive only noticed a pattern in the CPD mobiles so far. The mobile format looks like 5xxxxy. xxxx being the car number, and y being whether it's a regular car or a reserve car. This info is same as the wiki except the prefix is "5".
