With its unusual 3-way diverging junction and connecting curve, this is a most interesting location to operate. Here the main ex-Great Eastern line from London via Cambridge splits into the routes towards March, Kings Lynn and Norwich.
Many trains between East Anglia and the Midlands pass the box twice, before
and after stopping at Ely station, while other non-stop services use the West
Curve, which gives a direct link between the Norwich and March lines.
The simulation, in our Super Heritage series, features full manual
signalling, as used before the box closed on 25th April 1992, when Cambridge
Power Box took over control of the area.
