The "Roger Linn" (a 2-4-0) has been out of service since Nov. '07 after two leaky tubes, upon closer investigation, were discovered to be the result of a ligament crack in the rear tube sheet. Following a teardown and preliminary assessment, it was decided to replace rather than repair the current vessel and continue operating at reduced pressure in its current condition. I was the fireman its final day in service for the Carolwood event and, ironically, had one of my best days firing it ever (kept the thing within 2-3lbs. at all points throughout the day!)
Melodia/Frankenporter/Thumper/SMR recently received a tube job and is presently the only operable steam power on the roster. The Harpur, "Caroline," is presently off the property receiving a major overhaul.
One of the cars was renamed and the heraldry changed from Santa Fe and Disneyland to Santa Margarita's herald. That really broke my heart to see.
If it's any consolation, the new lettering on the 103 (in both places) is on placards placed atop the originals, leaving the original lettering undisturbed. This was done very early in the railroad's history—hence the "Avila Beach and Pacific Coast," which references a previous pipe dream of where it would all run. Subsequent work on two other coaches saw the SF&D lettering left as-is or restored entirely.
