"If Extra east 487-488 left Lava at 5:50 AM heading east, and Extra West 481 left Antonito heading west at 6:00 AM, just where did they actually meet? Or was there one heck of a cornfield meet that day on the narrow gauge that the orders don't tell us about?"
OK, a couple of slight posting errors here:
Extra 487 east wait at Lava should read 5:35 AM to 5:50 AM.
The departure time from Antonito for extra 481 west should read 5:00 AM. I misread the writing, the "5" is blotted in such a way that at first glance it appeared to be a "6".
That should make the trains get by each other in an easier manner.
Helper engine 488 had returned to Chama from Cumbres, times shown in orginal post.
