The MSTS Activity Editor allows you to make your own activities, or missions, for the player to complete. This is also how you can get lots of other trains running while you drive yours!
I was looking forward to this but Routeriter shows that I have a considerable amount of stock missing so it will have to wait until I can spend some time searching on the site.
I thought that I had a fairly comprehesive range of stock but it just shows how many people have been generous enough to design and publish all the stock now available on this site.
Carl Phillips is up there in the top 10 of my favourite activity writers. Im not surprised its a good one. Unfortunately i shan't be able to try it as I cant be bothered to download stock
Great activity, I ran it with one of the reskinned 50's just up on the BATS site. There is a fair mix of stock and I had a fair bit missing too, but it was easily swapped in conbuilder and I had no difficulty in running the activity. Well worth it!
