This evening there was what I understand to be a broken down train at Epping, right at the height of the evening rush hour.
Is this the correct reason for the power having been discharged and no trains between Woodford and Epping?
If it is the correct reason then surely it would have been better to just thin the service (more trains terminate at Debden, Loughton and even Woodford, with Hainault reversers stabled on westbound main) rather than close an entire section of railway at the busiest time. This would not have inconvenienced so many passengers - especially not those only travelling as far as Debden.
Or was there another reason which meant that discharging the power for a short time really was the only viable way to resolve the situation?
btw, this tweet is one that I saw had been sent to the Central Line twitter feed.

I believe the ERU had to walk to the stricken train to assist it. The juice was off because of this.

Simon The train appears to have become stalled over points. Could be any number of reasons - shoes missing, a fault with one or more units on the train, current rail(s) out of alignment, or even just the train stopped in an unlucky spot for some reason. It appears the decision was taken to use jumper leads to get it moving again, which nowadays requires the juice taken off - at least for the process of laying the leads onto the current rails. The traction current section is Loughhton-Epping, therefore running as far as Debden would not be feasible, apart from perhaps with the opening of section switches, which probably wasn't considered worthwhile for what should only be a short duration. I imagine most of the delay was getting suitably trained, qualified, licensed and familiar staff there. Leads is not something which can be done by either train operator or station staff. It has to be either a trains qualified manager (who in turn needs to be trained on the stock), or the ERU. The point about stock training is quite important, as on more recent trains (certainly on 95 & 96 stock, not sure about 92 stock) it isn't quite as simple as pushing the leads into the receptacle box. On 95 stock it's quite common for the box and its associated switch to get broken in the process if the staff don't know exactly what they're doing, which will then cause further problems. One also has to carefully choose which box will be used on the train - for example using the box on the middle motor cars on a 95 stock is likely in practice to be a timewaste! |
