Field Testing of visibility solutions for Freight Train Rear-End signals
Currently, within the EU both tail lamps and retro-reflective plates
are authorised as rear-end signals for international freight trains.
However, in some parts of the railway network only the tail lamps
are approved. When freight trains fitted with reflective plates
travel into these areas, the plates have to be replaced with
tail lamps,increasing crossing times and costs.
As part of a larger ERA project, OptiConsulting was
commissioned by SGS Correl Rail to plan and conduct field
tests to establish the optical performance of a number of
rear-end lighting solutions.The object was to see which
solution delivered acceptable visibility in a range of simulated
operational lighting and environmental conditions.
The tests were conducted over a 6-week period in a 200
metre indoor test facility. The lighting solutions included
LED tail lamps and retro-reflective plates (these lit by typical
train head lamps: halogen, LED and HID technology).
