This railway is HUGE!! The above screenshot centred on Reading is just a tiny fraction of the whole map, which covers practically all the GWR train operating company’s network. Accompanying it is the GW 2021-2022 Winter Timetable with about 2,000 services.
It is definitely not one for the faint hearted! Very slow simulation speeds will be needed most of the time in order to cope with the volume of traffic.
Platform numbers are provided in train descriptions for major stations.
