My guess
Mondays Train from Antonito
Tuesdays Train from Chama Double if needed
Wednesdays train from Antonito
Thursdays train from Chama double if needed
Fridays train from both Chama and Antonito
Saturdays train from both Chama and Antonito
Sundays train from both Chama and Antonito
All trains from Chama double headed in needed
10 trains per week
40 to 45 thousand passengers
This is assuming 3 locomotives. If 4 are available then departures from the other ends are possible on Monday - Thursday adding up to 4 more trains...ridership may reach 50K then
If gas keeps going up, then these optimistic predictions may have to be pared down.
