Just got a message from Scott Gibbs that the latest version on opening day is for 315 to run as helper to Cumbres, then run light to Antonito. Sunday 315 will take a short train back to Chama, following the regular train. An earlier plan had been for 315 to take the spreader back to Chama on Sunday, but 488 has already done that job. That is the latest at the moment, but I suppose that more changes are possible
