In this post, we will look at a few businesses in West Texas on the Texas Pacifico Railroad that need to move cars without the help of a locomotive. (The October edition of Trains Magazine has a nice article on the Texas Pacifico by Fred W, Frailey.)
Now we will visit an industry that had a much larger version of similar technology in Rankin, Texas also on the Texas Pacifico Railroad.
Badger Mining in Rankin, Texas received covered hoppers of frac sand for many years. It used a cable system to aid in the unloading of the cars. (Badger Mining relocated to San Angelo a few years ago. This facility is now operated by Halliburton.)
The rope is used to pull the steel cable back here so the steel cable can be hooked to loaded cars.
Empty cars after being pulled down for unloading. The cars were not uncoupled but moved together. Nine or ten cars could be moved, this was all the siding could fit.
Power unit is shown under shelter.
The roller lifted the steel cable over the unloading trough cover.
Two pulleys were required, one by the cable reel and this one.
The electric winch and rope on the right were used to pull the steel cable back down to the left. You can see the first pulley here just above the steel cable reel.
The motor on the left, the transmission to the cable reel, and the fuel tank.
When Haliburton took over the operation, things changed. The cable system was abandoned.
Note cable system is now deactivated.
This is how the cars are now moved at the Rankin plant.
Fort Stockton, Texas
The last company we will visit in this post is Texsand in Fort Stockton. Texsand also receives frac sand.
Like many frac sand dealers who have had to rush to meet demand, Texsand is challenged in having to transfer a great deal of sand from train to truck with minimum supporting infrastructure. Initially, Texsand used a front-end loader to move cars. That proved problematic fairly quickly.
After this, they acquired a track mobile.
The track mobile was a good solution until the volume exceeded what it could handle. At that point, the railroad began to switch the operation. Fortunately, they use mobile conveyors to transfer the sand, so locomotives are only required to move large cuts of cars.
Conveyors are common place in the sand business in West Texas. Today, at Ft Stockton, McCamey, Big Lake (above), Barnhart, and San Angelo, rather than move the cars to a unloading spot over a hole, mobile conveyors move from car to car and transfer the car contents to trucks. Since there are different grades of sand, cars are not always unloaded in order, and the railroad has to switch out the empties from the loads.
In the next post, we will visit how shippers along B. Smith’s LCN RR, tackle these challenges.
Until then, I will leave you with a couple of goodies (little modelling opportunities) I caught in Rankin near Badger Mining July of 2008…
I did a three part series on derails earlier this year.
This was on the side of an ATSF hopper in Rankin. Pretty easy to replicate.
