I have noticed that there is no services that call at Earlswood, salfords and Balcombe. In real life there is a few services a day that stop at these stations. I understand that the time table is very large and the team didn't have much time but all they had to do was add a few services that call at these stations
Yeah, they left gaps in the timetable so if they find that they can add in a Thameslink unit then it can just fill in those gaps as they would in real life
AIUI, Joe recreated every Southern service that runs on the BML, and even added a couple of non-standard "diversions" of GWR trains just because they were available. He included Southeastern 375s and 465s, some drivable: again, because they already exist. But TSW does not include any Thameslink rolling stock, so there is nothing to put on those services..
I know that thameslink run pretty much all services there but if you look at some stations services then about 3-6 southern services stop there each day
Figures taken from RTT Earlswood - 13 Southern services per week day Salfords - 12 Southern services per week day Balcombe - 5 Southern services per week day
