Regarding the leaving of equipment in signal systems, what is strictly prohibited?

Leaving standing engines or cars between interlocking signals is strictly prohibited because this practice can obstruct the view of signals for incoming trains and disrupt the safe operation of the railway system. Interlocking signals are critical in maintaining safe distances between trains and preventing collisions. Equipment left in these areas can lead to confusion for train operators and may result in unsafe conditions, ultimately compromising the integrity of the railway signal system.

This procedure ensures that signals remain visible and functional, allowing for proper train movements and reducing the risk of accidents. The regulation aims to maintain clarity in train operations and safeguard the infrastructure by ensuring trains can pass freely and safely without interference from stationary equipment.
