Choice of Route Like other recent routes for Train Sim World, this route wasn't previously featured in TS1 and was also previously proposed on these forums, showing that Dovetail is listening to the community. I would presume that part of the reasoning behind the date of 1989 is because of licensing issues with Northern Rail so a modern route may not have been possible. I think it was a good move to make this route set in 1989 instead of 1983 like Northern Trans-Pennine as it provides much more variety with the transition from BR Blue to the different Sectors. The Tees Valley Line has a much shorter length than other routes in TSW except WSR, only 27 miles. Whilst some people have complained about the short length of this route, I think that route length does not matter too much, but what the route provides is much more important. According to Realtime Trains, a stopping passenger service from Darlington to Saltburn takes around an hour now; during the 1980s this would probably have taken longer due to 2 extra stations and the Class 101 being slower than the Class 142 now used. The short length is also made up for by the many freight yards which will be included along the route, making this much more of a shunting and freight route than previous British routes for TSW. Choice of Locomotives The Class 37 in my opinion is a good choice for the route, allowing for more variety than re-using the Class 47 which has already been used on NTP and WSR. The loco looks great from the images shown so far. I am slightly disappointed though that it will only come in Railfreight Trainload Metals livery. Since it will be possible to drive coal trains along the route, I would have thought that it would make sense to add a Trainload Coal livery as well for the coal trains, something which I don't think would be very difficult. The Class 08 also looks very good from the screenshots. It is a nice addition to the route and will make use of the many yards, making them feel less empty hopefully. This will also provide the first UK shunting experience for Train Sim World, increasing the variety of services available. I was disappointed when I found out that the Class 101 would be featured instead of the Class 142 though it is understandable that the Class 101 is being re-used as there are already 2 new locomotives included with the new route. Hopefully, the Class 142 can be released as a separate DLC at some point in the future. Change in Route Cycle This is the first change in the cycle of routes from the US-UK-DE system used previously. Whilst this has been criticised by some, I think this is a step in the right direction with content being released when ready, instead of waiting for its turn in the US-UK-DE cycle. As long as there is a variety of content from the 3 countries featured so far, and hopefully more in the future, I don't think it matters what order stuff is released in. The Future for this and other British DLC This route seems to have good expansion potential, as well as potential compatibility with the Northern Trans-Pennine Route. As I've already said a Class 142 DLC would be good for this route and freight expansions such as a Class 20 would also be good for this route. Hopefully the next route will be a modern route. After 2 historic routes and a heritage route the UK needs more modern content. Whilst I don't think that it was a bad choice for this route to be historic, a third historic route in a row would be one too many in my opinion.
