Whoops

This was in GIF format so you could actually see it implode.

The tank had been steamed out and was still hot inside when a cool rain started to fall.
The tank had a vent designed to release pressure, not a vacuum.
Also the design of the tank was to operate at pressure and had no vacuum support rings on it. It can happen quickly.

Talk about being left deflated

I found this photo on "The Railway Eye" blog; I think someone will have a bit of explaining to do!

Where the heckythump was that?

Can't imagine an 0-6-0 doing that, did the other bogie do the same I wonder. I have often seen wheel burned rails but nothing on that scale.

wonder what the wheels looked like

Probably still round but rather hot!

A couple of years ago, maybe 10. I was working on a relay near New Pudsey station on the Leeds Bradford line when we dug out and relaid both lines through Stanningley tunnel.
As part of the work we installed brand new FB 113 rail on Concrete sleepers as per normal.
However at some point we asked a ballast train driver to draw forward wrong line towards Bradford, bearing in mind we were at the rear of the train expecting it to move forward, after a few minutes we called again asking when he would be moving, the startled reply "I thought I was" when we arrived at the engine a 37 there were 2 full bogie sets ( 6 pairs of burns) of burns in the brand new rail almost down to the bottom of the head. Another engine had to be used to drag the loco off the burns. Needless to say we had to replace the rails before we handed the possession back, luckily it was a week long blockage.
Question being why did he think he was moving when he wasn't?
Was he watching the speedo and not looking out the window? Was it a good day for page 3?

Long time since I got on a 37 but don't they have wheelslip indicator lights? - I seem to recall they did but must be 20 yrs ago at least. On the same subject I remember one of the p.way engineers at Watford complaining bitterly how these scoundrels of drivers were ruining his section of the West Coast Main Line with wheelburns. Think in this instance the real culprit might have been the DVT on a push pull set, if it was being driven from that end the drive couldn't know all that was going on with the leccie on the rear.

The wheelslip detection on 37s worked on an equalising wire between pairs of motors, if all wheels were slipping, no flow on equalising wire and no wheelslip light. If the train was in a tunnel it is very easy to misjudge any movement, there have been cases, I think one at KX, where a Driver thought he was going forwards when actually the opposite. Some Drivers would stick a shovel out to feel movement in bad conditions.

52A i think the tunnel incident you are thinking about may have been on the North side of the Forth Bridge. I dont have my reference handy but i think a train that was thought to be going forwards was actually slipping on the bank aided by wet and fish scales from an earlier freight. I will clarify this when i find the book.

Are you thinking of this, perhaps?

On 4/2/1945 2512 'Silver Fox' 17 cars 590 tons stalled in Gasworks Tunnel, King's Cross. The driver was unaware in the darkness and with the smoke and steam that the train was actually going backwards. It was derailed at the throat to King's Cross station and I believe that there were two fatalities when the train derailed, demolishing a signal gantry. The K/X signalman seeing the tail of the train reappear tried to set the road back into the departure platform ,but unfortunately the points changed between the bogies of the rear coach.

The 7/3/1954 incident was on a heavy up sleeper with A4 60024 in North Queensferry tunnel on the climb to the Forth Bridge from the north. On newly laid rails with a 20 mph PWS the engine,which was slightly overloaded, stalled and the train began to roll back and was derailed, fortunately without casualties. Again conditions meant the driver was not aware of moving backwards. After this incident marker lights were installed in the tunnel .The report on the accident attached no blame to the driver, noting the reduced adhesion on new rails as a contributary factor.

Thanks Bullhead but it is Stembok who got the 1954 incident which i was trying to remember. These incidents are clearly not that uncommon and the lights were a damn good cheap solution to the problem of indicating direction of travel.
