Answer: Stop immediately and contact the dispatcher
Feedback:When operating on any proceed indication that downgrades to a stop, the potential exists that another train or piece of equipment is now occupying that block. The signal could also drop as a result of broken rail ahead. Stopping is required to avoid an incident and ensure the safety of anyone working in those blocks. Contact the dispatcher so they can help determine the cause and provide instructions on how to proceed.
