hopper door operation

This is exactly the kind of story I like for the Arrow!  

No matter how long, or how short it is, real experience is better than someone’s best guess!

In a small shop such as Durham a laborer would sooner or later perform all of the various duties of that craft.  Some of my choirs took place at two short coal unloading tracks at this shop , each with a hopper underneath.  One track was for "yard" coal and the other track was for "road" coal.  The difference was that the "yard" coal had fewer "fines" and would burn cleaner than the "road" coal, which was probably like "run-of-mine" coal.  Of course the "yard" coal was used by the switcher locomotives to reduce pollution in urban areas.

I have knocked open both latches on a hopper door only to have less than a wheelbarrow load of coal come out of its own  accord. I could stoop down and look at a solid black wall of coal in the hopper opening.  My recollection is that this only happened with the "road" coal, and particularly cars that had been sitting loaded in the yard for some time where, presumably, rain washed the "fines" down into the hopper pocket where it packed against the then closed doors.  Our solution was to take large wooden mallets and beat on the sides of the cars with varying results.  Sometimes the coal right over the car's hoppers would eventually discharge leaving a block of coal at each end of the car that mallet blows would not discharge.  The solution in this case was to climb the ladder on the car with a long steel rod.  Once on top of the remaining coal pile we would jab the rod into the top of the coal just back of its face and rotate the rod backwards in order to pry off a vertical slab of coal (hoping, of course, that we would not go down with the loosened coal).

We would shovel "wet" coal into the top of the conical sheet and any sand that was dry would fall through the small annular opening between the bottom of the conical sheet and the hot stove.  We would then shovel the dried sand into the top of a tank that would later be pressurized to blow the sand through a hose into the sand boxes on the top of the locomotives.  Naturally, this operation had to be under cover, a true place for "sand house gossip."  Finally, try to visualize the comfort level shoveling sand in a small house with a hot coal-fired stove in the sweltering Durham summertime.

The hostler would monitor the build up of coal in the bunker and move the locomotive as necessary to leave an even pile of coal in the tender.

>> Oh my, this conversation brings back memories. My mom owned and operated a coal and feed store in Rural Retreat, from the early 40's until about 1956. She would 'buy' a hopper car full of coal, and have it parked on the siding, long removed, that ran southwest from a switch near the Depot. This siding extended past the south side of the Section House to where a truck rental business is located today. I recall them hammering the hopper door to open, allowing some of the coal to fall out onto a pile on the ground. Then, when an order for 'a half-ton' would come into the store we would shovel it into the back of the pickup and deliver it to some little house in a holler somewhere. We would keep removing the coal a little at a time, and more would fall out to replenish the pile. We would often use a sledge hammer to break up the big lumps into smaller lumps suitable for the numerous 'Warm Morning' and other coal stoves abundant in the area.  
>> The store name changed from T.F.Kidd and Son, to Akers Store in about 1946. I don't think Mom ever got paid for many of those loads. I have been curious about the cost of leaving the coal car parked for so long, as it could take months to empty it, a ton or so at a time.

>> As nearly as I can make out from pictures, there was a section of angle that spanned each pair of hopper doors.  The doors were held in the closed position by latches affixed to the outer sides of the hopper walls that held the angle.  My question is how these latches were released when it was desired to discharge the coal.  I see no evidence that the latches were connected from one side to the other, but it seems that if only one side were released, the weight of coal trying to push that door open might put considerable stress on the connecting angle?  Was the operation of these latches performed by men with pry bars moving them off of the angle?  For multi-bay hoppers, how would only opening a subset of the doors affect the coal discharge?  I've seen lots of footage of rotary dumpers in action, but the plain ole opening of bay doors seems to have escaped me.  Does anyone know of any video showing this operation?
