I did finally purchase the WCL, at 50% off in the sale, I didn't really intend to wait so long but between the amount of money I had and the long wait for a PC it seemed fairly pointless to pay full price this far down the line from release. Now I can't comment much on the route itself, scenery-wise I'm unfamiliar though I do have the two mods which supposedly improve it (though to what extent I have no idea) but it is a nice fun challenging drive with all the inclines. Now as for the trains again I can't physics-wise as I have little knowledge in that regard but I can say in regard to the 150... I get it. I lived in Manchester for three years and the 150s were among my most frequented trains during that time. I'm sure there are many finer points others have already picked upon which I haven't really noticed but the big issue, accelerating from a standing start the noise is jarringly absent, it actually seems to get quieter than it is when idling. I just find it incredibly unsatisfying when my ears expect a cacophony of noise and instead I get nothing. I certainly hope that if and when we see another Sprinter more consideration will be taken into such an iconic aspect of their sounds. I will say the extra layers are a mixed bag for me I'm happy with the 101 and the 47 being on there even if the 47 isn't necessarily the ideal livery. The Mk2s being the wrong type does bother me slightly but I think with the somewhat disappointing nature of the main train of the route I'd rather have the wrong Mk2s on the expresses than no expresses at all but give them brake coaches, please! As for the 40 and 45... no, I don't want them on the route at all, it's one thing to add trains new types of service but with the 40 and 45 it's just adding trains for the sake of adding trains where they don't belong and I say this knowing full well that those two are among my favourite locomotives in the game. The Tees Valley 37 being an option on the route is a nice touch too but it does seem a bit weird that these can't be used on the engineering services on the timetable. As for looking beyond Cornwall, I hope the WCL 37 is enabled for the Tees Valley Line and some engineering runs or having the wagons as the scenery on that route would be a nice touch for future updates. However, I don't want to see the 150 on NTP and WCL, not because of the disappointment of the train but because it would not be appropriate to do so. Oh, and as a pie in the sky idea, a 'Diesel Legends' style 1970s timetable for WCL with the various pieces of Blue locomotives and rolling stock would be great fun. Overall, although I do think I will find plenty of enjoyment from this route there are areas that fall short of the mark for me, in particular, the 150 sounds and the rather confused layering which will probably stop the route from being in my go-to list which NTP and TVL firmly dominate.
