REF Forums -> Hobbies -> Train Sim World -> Getting Started ->Guide On Route Acronyms On SFJ with the MP15DC there is the service Extra 07 (Resuce Failed Train). While you can do it, you must do the first two orders as fast as you can (stop at the certain point and go via the other certain point). If you do not do it as fast as you can another train enters the block and will lock the switches which in turn prevents you from completing the service.
