My understanding of approach control signals on National Rail is that drivers are not required to know which signals are approach controlled, and indeed there is a degree of encouragement not to do so as a driver may assume an approach controlled signal will clear when it won't.
However, from playing the Metropolitan Line in Train Simulator, approach control signals seem to work differently on LU, and I'm wondering if this is accurate or a limitation of the simulation. They appear to require the driver to drop below a specific speed by a certain point before the signal, and even if the driver stops short of the signal if they exceeded the prescribed speed over the aforementioned point before the signal the signal will not clear. The locations and prescribed speeds are not marked, thus necessitating drivers to know which signals are approach controlled and what speed they mandate. Is this accurate?
