CCG/Kind: Engine
From TrainzOnline

KIND: ENGINE
An engine file specifies a traincar's performance and physics parameters. TRS also supports steam physics and thus, steam engine files have additional fields for this. The following examples are of the SD40-2 Diesel locomotive and the PB-15 Steam locomotive.
WARNING: ALTERING ENGINE FIGURES MAY RESULT IN UNDESIRED EFFECTS IN PERFORMANCE AND BEHAVIOR OF YOUR TRAINS.
(MAKE BACK-UP COPIES OF YOUR ENGINE CONFIG FILES!!)
