In TRS2019 I had to switch to paulhobbs' "Crew figures, driver left, medium cab" <kuid2:44090:628:40> from the "Crew figures, driver left, medium cab" <kuid2:44090:89:1> which is the dependency in the BR 5MT file downloaded from the Downloads/Content page on the Trainz Simulator 2009 Settle and Carlisle site. Both files are payware, though I can't recall if the 628:40 comes from S&C, PLL or somewhere else. If (for some reason) S&C is not an option for you then GP Locomotives has a 5MT payware loco range.
