What is the maximum allowable speed in ATC Bypass mode?

The maximum allowable speed in ATC Bypass mode is set at 40 mph. This speed is established to ensure safety and maintain effective control over the system during bypass conditions. ATC (Automatic Train Control) Bypass mode refers to a state in which the automatic control features are temporarily disabled, allowing the operator to directly manage the speed and operation of the train.

Setting a maximum speed of 40 mph helps mitigate risks that could arise from running at higher speeds without the full automated safety measures in place. It reflects a balance between allowing operational flexibility and ensuring a conservative approach to speed limits under potentially less controlled conditions.

Overall, this limit is critical for ensuring both passenger safety and the integrity of the rail operations when automation is not in effect.
