D&RG Class 125

The Denver & Rio Grande Class 125 is a 2-8-2 locomotive. It was added in The Winter Update.
== General History ==
In 1901, the Denver & Rio Grande Western had put in an order for a set of 14 Vauclain Compound 2-8-2 Mikados from the Baldwin Locomotive Works, following suite two years post of the order, the locomotives were built between February and April 1903 and delivered to the D&RG. Baldwin Specification Sheet for the Class 125, Volume 25, PDF page 157 Engines 450 - 464 were quite the engines for their time, originally designed for taking the challenging 4% gradient of Marshall Pass. Later on, the Rio Grande Southern had purchased 455 and 461, and the N de M purchased 458 and 459.Locomotives of the Denver & Rio Grande, A. B.

=== Brief Technical History ===
The hefty 2-8-2s rode on 40in driving wheels, and built with Stephenson valve motion in correlation to the Vauclain compound. By 1907, they started converting the the locomotives to conventional slide valves, but retained the old Stephenson valve motion, with all locomotives being converted by 1909. Due to the conversion, the locomotives lost quite a bit of Tractive Effort, but were still very capable engines. Between 1924 - 1929, all but 450, 451, 457, and 460 were converted to Walschaerts valve motion. Denver & Rio Grande Western K-27 Mikado Engines #450, 451, 457, and #460 were retired from service in 1932 and later scrapped in 1939. The rest of the class were retired between 1950 - 1962 with engine #464 having the honor of being the last locomotive to retire from service. 
=== Paint History ===
As-built, the locomotive was painted in Baldwin Style 261, the same as Paint No. 1 in-game, albeit the engine had matching lettering to the paint. This paint scheme had only lasted a week, and was quickly painted into what Paint No. 2 represents. The locomotives all lasted in this paint all the way up until retirement, with their tenders and tender lettering changing over the years. The latest variant of the Class 125, re-classified as the K-27, got the standard tender tank design as we now have in preservation, with the flying Rio Grande font painted across the sides of the tender saying "Rio Grande", the same mannerism as was present on the other narrow gauge engines of the D&RG. 
=== The Prototype in Preservation ===
Today, you can see two of these wonderous machines in operation in two different states; D&RGW 463 on the Cumbres & Toltec Scenic Railroad, and D&RGW 464 on the Huckleberry Railroad.
== The Model In-Game ==
In game currently, we have the as-built model as it was in 1903, with Paint No. 1 being Baldwin Style 261, the as-delivered paint, Paint No. 2 representing the week change over. The other paint schemes provided are fictional representations, with the 5th option being a part of the "Lake Valley" scheme series, fitted to a handful of the engines in-game.
=== Modeling the Prototype ===
In the game, the locomotive is set up to be made as the as-built version of the engine with the paint change. The format is as follows;
Number: 450 - 464
Name: D. & R. G.
Tender: D. & R. G.
Paint: 2
Stack: 1
Headlight: 1
