One of the train features that my guests have liked the most is the VL Big Boy's depleting coal load, followed by the refilling (reloading?). At the start of the run I ask them to look closely at the coal tender. Then, after running for 10 minutes or so, I stop the engine so they can see how the coal ‘has been used up’. Then, I refill the coal.

 

In real life, was the coal loaded in the tender at the beginning of a trip, as when leaving the roundhouse, or when the locomotive returned, so it would be ready for the next trip? I understand that in a long trip, the coal may have been reloaded several times along the way, with many more water refill stops.

 

Thx!

Yes.

or when the locomotive returned, so it would be ready for the next trip?

 

Also, yes. Many time the coal was "topped off" immediately prior to departing the locomotive servicing area, even if it had been filled upon arrival. Same applies to the water in the tender.

Correct.

But in the "real world", there would have been no way to refill the locomotives tender UNTILL it got to the "roundhouse area", as that would be were the huge coal dock was located.

 

This will be easy to demonstrate, i.e., start with a tender full of coal, and at the end of the trip the depleted coal can be restored to full level.

 

Thanks!

So let's take this a step further- it's not represented in our models but can anyone answer how aux coal/water tender loads were transferred to the front? Water I would presume had flexible lines attaching to the main tender but coal??  

P.S. Tv's used to have wood grain cabinets and dials that you had to get up and turn to change stations....just incase the youngsters were wondering.

Yes, 3" to 4" flexible hoses with cam-lock fittings transfers the water from the auxiliary tender to the main tender. Also, 2 1/2" firehouse fittings have been added to both the main tender and auxiliary tenders, down low at frame level, for easy connection of 2 1/2" fire hose to any nearby hydrant.
Naturally, there is no coal/oil fuel in auxiliary tenders since fuel would be able to transfer. Besides, there is a ten to one ration for water consumption vs. fuel consumption, thus the requirement for LOTS of extra water.

Alex,

  In the early days the coal was refilled when the train passed the different coal and water station stops on the line, the trains stopped at the different locations depending on the size of the boiler and the size of the tender, and how the trains were routed on their schedule.  All this was figured by the train scheduler & router, along with the turn out controls.  The train conductor had a big part in making sure how all this got done, as the trains moved down the line & kept schedule, in the early days of railroading.

That depends on what era you are referring to. Generally, coal was not taken enroute, as the early 20th century railroads tended to changeout locomotives at the ends of their runs, based on fuel supply and lubrication requirements. In the more modern era of "big steam", such as the original poster's question about his UP Vision Line Big Boy,  coal was not added enroute, except ascending Sherman Hill. Water, however, could always be added at many different locations enroute.

Hot Water,

   You are absolutely correct, this also had to due with the size of the RR and how big the engines and tenders really happened to be, the smaller mountains railroads had to use many coal stops, where the bigger flat land RR trains hi balled it to and end refueling stop, many different things were done in different eras to make the trains run in an economic manner.

NH Joe

Some railroads did change locomotives at major terminals enroute. Since you mentioned the NYC, the modernized Hudsons ran all the way to Chicago, as they could scoop water from track pans. Coal was taken on in Cleveland at a main line coaling dock. Another example would be the Southern Pacific Coast Daylight passenger trains, with the GS class Daylight locomotives running through from LA to San Francisco. At the halfway point, San Louis Obispo, the locomotive was refueled (oil), lubricated, and refilled with water.

the GN was a good example of this practice.  it was based on the terrain to be crossed and fitting the locomotive to the task.  most locomotives never left their division.  on the Empire Builder, i believe there were only two divisions where the larger S2 4-8-4's were used.

 

the NYC from NY to Chi had the benefit of a water level route for the entire run.
