There is a small majority who don't like modern content. They rather have historic unreliable plastic
To be honest some, but not all, old trains can be unreliable but there are some that despite being just plain and supposed to only last a couple of years (looking at you Mr.Pacer) managed to stay in service for over 30 years! But anyway, back on topic, I do fully support the London-Brighton Line and definitely feel it should make an appearence in TSW2 either modern or historic. Or maybe during a switchover period from the good ol Slammers to the new stock (well new for that period anyway) so there can be a best of both worlds. And a final note, if the Gatwick Express licence is ever aquired, DTG please do the Plastic Pigs (442s) in Gatwick Express Livery!
That’s why they are making the 70s BR Blue pack for GWE, so they can make everyone happy (there will always be a few who will complain though)
