When the 31 and 20 were preserved I was disappointed to find that these locos didn't come with coaches despite them being used in various service mode timetables. It would be great to see both locos come with MK I and MK II coach varients.
I agree. Class 37 as well. Also all of the British diesel locomotives in TSW were used on freight but there are no freight options for some of them in scenario designer (cl33, 52 for example)
