On the Banbury stone...


Recommended Posts

Hi Matt, the hopper wagons are fitted with a continuous rubber belt (they're in sets of five) that takes the stone along to the unloading chute... we unload ten at a time, put the jib back in place, fetch the next set of ten and swap the chute over and so on and so on... unloading on the move is verbotten(!),

 

The same wagons were sometimes used to deliver ballast to track relaying sites, and we did sometimes unload them on the move.

 

Control was difficult as there was a delay caused by the time taken by the stone to travel down the belts before any change would happen. So we would control how much stone landed in any one place by asking the driver to speed up or slow down the train.

 

You also unloaded away from the ends of the job, unless you wanted to risk burying the adjacent track.

 

Proceedure was.....

 

Set up unloader at end of job,

Belts running,

Agree with driver which way he was to go (into job), how fast and that he was ready to bib his horn and move on comand.

Warn Redlands train crew and anyone else on site that the train is about to move in X direction with no further warning.

Ask Redlands train crew to start unloading ballast.

Once you have approaching the right amount of stone at the start of the job, ask driver to move.

Follow unloading arm down job altering the speed of the train, so that about the right amount of stone is dropped at any point.

Ask for stone discharge to be stopped well before end of job.

Once belts are empty and no more stone is being delivered, set train up at the other end of the job and reverse procedure.

 

If this sounds too easy do at night with limited lighting.
