DTG having evidently lost its interest in those who, like me, prefer switching/shunting work to more basic passenger and freight runs, I've started looking at Trainz again, where I recently bought the Potteries Loop Line route [https://store.trainzportal.com/products/potteries-loop-line-1?utm_source=content_store&utm_medium=link&utm_campaign=trs19_ingame&utm_content=696] . Take a look at this description: "There are no less than 35 sessions provided with the Potteries Loop Line. 11 are associated with the Signal Box Rule whilst the other 24 cover different areas of the route, mostly servicing the industries already described and exploring the private and industrial lines that proliferated in the Potteries up to the 1960s." So far, I'm still learning the ropes, but having a great time doing so.
