AT&SF class 3700 "Whyte notation" 4-8-2 "Mountain" type steam engine used by the road to haul passenger trains and fast freight traffic. The "Mountain" type, in North America, appeared around 1911 on the Chesapeake & Ohio. They would be found working up to the last days of steam, in the United States, hauling the short fast freight service and mixed trains until replaced by diesel power in the late 1950's

AT&SF class 3751 "Whyte notation" 4-8-4 "Northern" steam engine used on the road for the same type of work as the Class 3700. The Northern type was brought onto the Santa Fe around 1930, to supplement the older Mountain type engines in pulling the road's passenger services. They had more pulling power and traction effort then the 3700s. As these "Northern" locomotives came on the main line they took over the main passenger traffic until diesels supplanted them in the role, and like the older engines, they found themselves pulling the "hot shot" fast freight into the 1950s.

i have used some terms here, that some people, might not be familiar with. so i thought I would sort some of it out here...
Of course we know what passenger service is. this is movement of people by train...lol. but in this area you have various services such as Primary and Secondary trains. Primary trains are your long distance services that have sleeper cars and so on..."Hotels on rails". Secondary services are your more economic trains. Examples of this on the Santa Fe would be the Super Chief and the Chief in the steam era. They ran the same line, but the Super Chief had sleepers and Pullman service, while the Chief was made up of coach cars: both had observation and diner cars. Later in the diesel era, the Chief was replaced with the El Capitan. Then you had the unnamed locals that stopped at every town along the route. The roads mainly made their money of these trains, not by carrying passengers, but by carrying the Mail.
The other side of the business was the freight: movement of goods and consumables. On this side, you had the slow freight trains, and the fast freight. Those terms explain themselves. in the early to mid 20th Century, the roads made a good use of "older" passenger engines by assigning them to trains that could pull priority cargo at the speeds of passenger trains. These "Hot Shots" lasted until trucks took over this business in the 1960s, but even today you can still see short fast freight trains, but well those are the rarity. Slow Freight was used to move massive amounts of goods at a reduced time schedule. These are your long trains in the steam era. These fast and slow freights are often called "manifest" trains.
In the freight trains, you might see an engine pulling a string of one type of cars. these are "unit" trains. An example of this kind of freight is a "coal drag" consisting of open hopper cars loaded with the same type of coal...
Many of the locals, in the US at the time, were "mixed" consists...meaning they moved both freight and passenger services behind an engine at the same time...
Just some terms for us to keep in mind...

AT&SF class 3400 "Whyte notation" 4-6-2 "Pacific" type locomotives started to appear on the route around 1919 for passenger service. These Pacific types pulled the mainline passenger services into the 1930s, when they were replaced with the 4-8-2 and 4-8-4 types: they were then moved to yanking local and mixed trains into the 1950s.

An example of a unit train, being pulled through the Tahachebe Pass...this double header is pulling 35 reefers and the caboose... Southern Pacific class F3 "Whyte notation" 2-10-2 "Santa Fe", but called Decks (for Deca, in regard to the ten driver wheels) by the engineers of the SP, because they just couldn't call them a Santa Fe. These engines became on of the primary freight haulers of the Southern Pacific, and there were five different F classes of this type...They stayed in service until the mid 50's... You see i also like other roads besides the AT&SF!!!
