On non-signaled sidings, the speed must not exceed which value?

Explanation:
The key idea is that on tracks without signals, you must operate at a speed that allows you to stop within the distance you can observe and react, since you have no signaling to tell you when a block is occupied. The standard limit for non-signaled sidings is 25 mph, which provides a safe balance between efficient movement and control around switches and potential obstructions. Faster speeds would risk a collision or derailment if an opposing train or obstacle appears, while much slower speeds (like 15, 10, or 5 mph) are generally reserved for certain yard or restricted-area situations rather than the main non-signaled siding itself.
