315 does not have a flange oiler, so the painted admonition is not applicable. There is an intention to build and install a flange oiler at some time in the future. Drawings have been made from the 346 flange oiler.
As for Rich Muth's photos - they are great, especially the last one with the snowy peak. I left Chama Thursday afternoon as 315 was building up pressure, so missed Friday's test run (which was to happen Thursday if not for a leaking dome gasket that had to be annealed and re-installed).
315 is still scheduled to doublehead with either 484 or 489 Chama to Cumbres on opening day, continuing to Antonito
