Derailment of empty passenger train at Paddington causes major disruption - 16 June 2016

[whole diary]

Ah - cost - of course. Yes - get catch points to derail a train straight into a supporting gantry of power-lines carrying thousands of volts - just enough to cause a major fire of spilt diesel fuel. Ah - but we had that a few years ago didn't we?

It appears that lessons have not been learnt. It doesn't exactly enhance any feelings of safety when such an incident occurs - by deliberate design. I wonder what the cost for all this will be?

The fire you refer to I think was Ladbroke Grove, that was not caused by the OLE^▸ (Overhead Line Equipment, more often "OHLE") arcing, the protection works to fast for it to ignite diesel . 

Yes there are thousands of volts 25 thousand to be precise, there have been no known incidents of passengers or staff coming to harm from the OLE when it has come into contact with train carriage; there may be a load bang and folk my need to change their underpants but they not come to any physical haram form the electrical energy.

Journey check now saying disruption till 0200 20/6, unable to run a normal service "until further notice"-whatever that means.

Is it too early to start querying how many void days gwr will volunteer for this disruption? My money is on... None.

[LiskeardRich]

90 cancellations today and 125 service alterations. The joys of being up early means seeing journey check for the whole day, rather than just remainder of seen later.

I have to go into London from Thatcham on Monday. I normally leave extra time in case of the odd incident but may have to be extra cautious. Let's see how the weekend pans out.

I wonder if the ORR^» (Office of Rail and Road formerly Office of Rail Regulation - about) Inspectorate have released the scene to NR^» (Network Rail - home page) yet?

The derailed train its self is not the problem. although it caused the problem!  The problem is the OLE^▸ (Overhead Line Equipment, more often "OHLE") structure which is a twin track cantilever which not only registers the wires into plat 2 which would normally be dealt with by pulling the wires out of running with strops and pull lifts; the main problem is this structure J/00/42 is also the counter balance anchor for the crossovers in the area, this is a little more tricky to deal with, I suspect the canopy of plat 1A will be used as a temporary anchor.

The damage to the foundation of J/00/42 will need to be assessed once the unit has been recovered new foundation bolts will almost certainly be needed these are normally 22mm dia but can be 32mm.

.......you took the words right out of my mouth!

I remain fully aware of two thread - and aware of repeated notifications to that effect. Somehow the two thread, same topic stuff feels trivial tonight - see http://www.firstgreatwestern.info/coffeeshop/index.php?topic=17162.msg197342#msg197342 . I'll sort it in the morning.  In the meantime, please feel free to carry on posting in this thread.

A word of praise for your separating of these two threads - well done, and many thanks!

The thanks are due to Chris from Nailsea - THANK YOU Chris

Oh and it should be said the structure anchor bolts are about 1500 to 2000 mm long, the foundation will need diamond core drilling

I forgot to mention on Friday that I saw a Greenford service in the new (and what I thought was the still unfinished) bay - Platform 5 - at West Ealing.  Was this use planned or was it brought forward because of the derailment? RTT^» (Real Time Trains - website) shows it in use today.

Engineering work between Bath and Swindon taking place as planned but the Bristol and Bath to Paddington via the diverted Berks and Hants route no longer running with all services running via Badminton. Bath passengers to/from London advised to travel via Bristol with GWR^▸ (Great Western Railway) operating an HST^▸ (High Speed Train) shuttle service between Bath and Bristol.

Journey planners aren't showing this. Instead showing bus to Swindon or travelling via Westbury to join already very busy West of England services.

Certainly a lot of West Ealing terminators ... I suspected they were using the bay!    It will be very interesting to see the effect on traffic on the Greenford line of the change.

Thanks to CfN for reorganising the two threads.  No easy task to move such a large number of posts from one thread to another.

[Chris from Nailsea]

Thanks for the thanks. 

It was indeed something of a challenge - but not perhaps as much of a challenge as fixing the physical damage caused by the incident itself.
