The Class 43 InterCity 125 is a diesel locomotive manufactured by BREL, in use on Stepford Express. Two of these locomotives top-and-tailing four Mark 3 coaches can be purchased for 2250 points (3000 normally). When the train first came out it was only 2400 points and that was until 26 December 2019.
