It won't necessarily have the headcodes for freight services - many operators do not provide full data, so RTT "invents" a code for the train.  However, knowing the scheduled train times, you can always have a rummage in the WTT to find the actual identity of the train.

GBRf is one of the few freight operators for which correct headcodes are provided.  You'll also find that, for GBRf, RTT will give you the identity of the loco working the train in most cases!
