And to answer another question, I doubt that it had much to do with adding "Western" since D&RGW was incorporated in Nov of '20 and took over the property in Aug of '21. More a sort of general shake-up/housecleaning. as bunches of std ga were also renumbered including all or parts of clases s-19, s-23, t-17, t-18, t-19, t-24, t-26, t-29 (only 4 of 34 renumbered), s-33, g-20, both classes of g-28, c-14, c-26, c-28, c-16-80(the ex San Pete RR engines), c-38, c-39, both classes of c-40, both classes of c-41, p-44, f-81, L-62,and L-96

based on weight at time of purchase, there were changes over the years.

69,110 lbs by the 20's

Oddball (soon-to-be)c-17s & c-18s were listed as classes 71 & 72 in timetables of 1923 vintage. 1887 engines were still class 70. All of these were listed as 14 tons better than orig. class 70's (later c-19) on 4% grades (106 tons vs. 92)

wts:
c-17-70 70,300
c-17-71 71,100 (#306 I don't have a listing for #305)
c-18-72 72,000
c-19-74 74,260

c-21-93 (formerly class 93) 95,650
c-21-112 (formerly class 112) 117,400

> K-27s were originally class 125.
1929 wt 136,650 (140,250 for engines with sh)

k-28-148 (formerly class 148) 1929 wt 156,000

not quite right:

After the class 42 (wt 40,000, but there was already 2-6-0 class 40) 4-4-0s the D&RG experimented a bit...

#'s 150-154
Class 45 2-6-0 drivers 45" wt 52,000 te 9500 baldwin 1881 [1]
all gone by '02

#'s 158-165[2]
Class 45 1/2 4-6-0 drivers 45" wt 53,400 te 10,503 bladwin 1882
3( 158, 159, 165) went to D&RGW then to RGS (RGS (1st)22, 23, 24)
all gone by '16

#'s 166-177
Class 47 4-6-0 drivers 45" wt 56,550 te 11,590 bald. 1883-1884
these are the t-12's (1929 wt 70,550)

Don't forget the 0-6-0Ts and the Farlie!

pedantically yours,

[1] Palmer seemed to like the idea of Passenger 2-6-0s, the RGW (std ga) had 10 of em in 2 classes, purchased 1898-1901.

[2] #'s 155-157 went to class 46 baldwin 1881, basically class 45 1/2 engines built to std ga. reno 503-504 in 87, all gone by 1906.
