What is the maximum speed allowed for a key/alert train until further testing?

The maximum speed allowed for a key or alert train until further testing is 30 MPH. This speed restriction is put in place as a safety measure to ensure that any potential issues can be managed effectively while the train operates under heightened scrutiny. It allows for a controlled environment where more data can be collected and evaluated regarding the train's performance, equipment functionality, and overall safety measures before increasing the speed.

Management of the train's speed at this limit is vital to mitigate risks during the testing phase and ensures that operators can respond quickly if any situation arises. This cautious approach aligns with safety protocols that prioritize the protection of both passengers and the railway infrastructure.
