With the NTP line coming out, and also TVL line. I think it would be nice to add a couple more railcars to the mix. For instance class 104s which were a major player in Northern England, with a few still running in preservation. Especially on the Llangollen and East Lancashire Railway. Another, although I am not sure if they opereated in the North East, is the Class 108. These units looked a bit more modern inside. Also the two i mentioned could be coupled up with each other and in some cases even have hybrid sets. Such as a 104/101 2 car set. Just a thought.
Class 123 and 124 sets would be great additions. The 123's were transferred from the WR and the 124's were purpose built for Trans Pennine services.
Totally agree with the idea to release a pack in the same format as Heavy Freight. A pack of this kind could feature the following... Class 123 Intercity DMU at West Ealing prior to being placed on the Transpennine route. Class 124 Intercity DMU purpose built for Transpennine services. Class 128 Parcels DMU. Class 141 Railbus DMU as used on Huddersfield to Leeds Services. All these types were in use at around the time that NTP is set and would create some interesting drives.
Found on Flickr Huddersfield 1984 class 101 with a 108 next to it My photo of a class 104 at Bury. Another class I suppose that could be added is the class 110 Calder Units.
Great ideas for the Class 104, 108 and 110. The driving dynamics should be incredibly similar to the 101 and hence not too hard to achieve.
More DMUs for NTP in particular would be great and would add even more variety to the route, especially if they add more services. I personally would like to see a class 123/4, with them being quite a unique DMU which would also add more express services on the route.
