En la penúltima semana de julio fui en busca de un geocache al Parque Liberación motivado también por la exhibición del tren de vapor y la ubicación del geocache en el mismo. El tren se encuentra ubicado a pocos metros de la entrada ubicada en las coordenadas 20°38'8.35"N 103°20'36.70"W
Tren N. de M. 3027 Niágara
Este lado del parque se encuentra descuidado. Podría decir que todo, sin embargo me llevé la agradable sorpresa que en el lado oeste fue arreglado y hay juegos infantiles de muy buen gusto.

Pero regresando al museo del ferrocarril, el cual deja mucho que desear para ser llamado museo, la máquina es la tercera de las 32 construidas por ALCO (American Locomotive Company) y fue puesta en servicio entre agosto y noviembre de 1946. Su presión de trabajo era 250 psi y tiene un peso de 285 toneladas. Su factor de adhesión, 4.2. Esfuerzo de tracción en un 85%; presión de la caldera, 57.000 libras; 2800 caballos de fuerza; 25 "x 30" cilindros; engranaje de la válvula, Walschaert; freno automático de aire, Westinghouse ET-8; altura total 15 '4 7 / 8 "; rodamientos Timken, banca de motor integral; capacidad de agua, 15.000 galones, 6000 galones de petroleo; distancia entre ejes rígidos 18 '3 ", compensados 12' 2"

4-8-4 "Northern" Type Locomotives
The 4-8-4 was the ultimate wheel configuation for the modern passenger and fast freight steam locomotive. The eight driver arrangement was usable on almost every main line in North America and with drivers up to 80 inches in diameter allowed any reasonable speed that the railroad could handle. The four wheel trailing truck supported a larger firebox for maximum steam levels allowing for extra boiler capacity. The four wheel leading (or pony) truck completed the best combination for riding and tracking.
With the surge in passenger business in the 1920's most railroads were being forced to operate extra trains or run their scheduled trains in sections simply because the locomotves in use could only haul about 12 cars. It was out of this need that the "super powered" locomotives were developed and of them the 4-8-4 was the most numerous and widely used.
The first 4-8-4 was built by the American Locomotive Company, in January, 1927, for the Northern Pacific. This locomotive was basically the 4-8-2 modified to accomodate a large grate area and a very deep firebox which was required to burn the very low grade of bituminous coal that the Northern Pacicific produced from its own mines. This new wheel arrangement was dubbed "Nothern Pacific", which was quickly shortened to "Northern".
There were 36 North American Railroads that owned and operated a total of 1,126 "Northern" type locomotives.
Some railroads, particularly the southern ones, rejected the "Northern" name and used names with a more regional connection. The C&O called them "Greenbriers"; the Delaware, Lackawanna & Western used the name "Poconos"; the Lehigh Valley came up with "Wyoming"; the Nashville, Chattanooga & St.Louis named them "Dixies"; the New York Central chose "Niagaras"; the Richmond, Fredericksburg & Potomac named each of its 27, 4-8-4s after southern generals, governors and statesmen; the Southern Pacific used the name "Golden State"; the Western Maryland dubbed them "Potomacs" and in Canada, the CNR named them "Confederations" while the Nacionale de Mexico called them "Niagras".

Como ya les mencionaba, el geocache se llama Reliquia de Vapor y la dificultad para encontrarlo es media alta. Se recomienda para los que ya tienen experiencia buscando geocaches. Sin embargo, si se es observador y usan su sentido común, probablemente lo encuentren aunque sea el primer GC. Una buena pregunta para encontrarlo es: Dónde lo escondería yo de tal manera que no lo viera nadie y estuviera al alcance sin hacer algo ilegal?
