What is the speed limit for a train traveling in river tubes?

The speed limit for a train traveling in river tubes is typically set at 35 MPH. This speed limit is established to ensure safety within the confined space of the tubes, where factors such as ventilation, emergency response, and overall train handling require more cautious operation. At this speed, train operators can maintain control of the train while also ensuring the safety of passengers and infrastructure.

Higher speeds would potentially increase the risk of incidents due to limited maneuverability and reduced time for response should an emergency arise. Therefore, the selection of 35 MPH aligns with safety protocols and operational procedures designed for trains operating in such environments.
