Re: Como surprise / Mason Bogie locomotive lettering.

a few notes/quibbles:

1) 1885 renumbering was a system-wide UP renumbering to get all the smaller railroads owned by the system into the number scheme. These were the numbers most of the engines carried until the C&S renumbering in 1899-1900.

2) Last Mason were delivered in the Fall[1] of 1880. At least 6 of the "cold-water" Brooks 2-6-0's of 1882 had names.[2] So Kate being the first named "since the Mason Bogie days" would seem to depend on how you're defining Mason Bogie days?

3) While I'm playing, I've always wondered about those Brooks. the 4 apparently un-named engines includes the first of the series, #29, while the last is named. They are numbered, and were apparently delivered(5/82-9/82), in Construction(builders) number sequence. I've wondered for many a year if the other 4 engines also had names when new and we just don't have a record of them.

4) Also worth noting, the Brooks were the only named engines delivered in the UP era and 2 groups from the Evans Era had no names![3]

[1] 2-8-6T #29 "Denver" 10/1880, Last 2-6-6T was #24 "Buena Vista" and/or #23 "Grant" both 2/1880
[2] #30 "Morrison", # 31 "Hill Top", #33 "Webster", #34 "Alma", #35 "Dillon" & #38 "Chihuahua"
[3] The ex C&StL engines, #'s 17-19, Dawson & Bailey 2-6-0's, to DSP&P 11/1879. Interesting (to me at least) trivia: AFAIK these had the largest drivers on any 3' gauge engine used in Colorado, 47". South Park line, as far as I can tell, mostly used them as switchers.
#'s 50-57, Baldwin 2-8-0's delivered 1-2/1880.
