Passenger Safety Surveillance System.
Nemacom 12.1” LCD monitors have been selected for use on the new Bombardier “S” class rolling stock being introduced on the Metropolitan, Circle, Hammersmith and City lines. 760 monitors are currently being integrated within the driver’s cabs on the 192 strong fleet of state of the art underground trains.
The custom designed LCD monitors are used to display CCTV platform images when the train is approaching, whilst stationary and when exiting the station. Since the trains are used both underground and on surface lines, Nemacom had to overcome some demanding challenges to ensure the displays were crystal clear in bright sunlight and subdued underground conditions.
Additionally, the displays had to meet London Underground approvals for EMC emissions, immunity, shock and vibration to ensure suitability for long term use in a very demanding environment.
