Is there an issue between Taplow and Maidenhead on the Up main that causes Class 800 drivers to brake to around 110mph? I didn't see any TSR's posted for this. I know there is a neutral section after Maidenhead westbound and the 800's aerodynamics see it shed more speed than a 387 through there!

Do u mean the down? As there is an ATP fault between those two stations which causes the brake to apply briefly , though is on the down main not the up....

Key thing today was that it ran up and down the bank between Exeter St Davids and Exeter Central, whereas the last run came in from the east and turned back at Central.

The route is presumably now cleared for IET diversions between Exeter St Davids and Castle Cary via Yeovil, in time for the closure of Whiteball Tunnel for maintenance work in February and early March.


First IET in service today via the Mule as diversion due incident blocking line.

I thought it was the 1656 Cardiff - Paddington with the air leak or was it the same fault on 1629 Swansea and 1656 Cardiff? 1556 Cardiff also failed on the starting blocks.

1L86 16.29 Swansea - Paddington shown as 800011 & 800012.

1L82 16.56 Cardiff - Paddington was 802103. (Cancelled from Bristol PW)

Both showing cancelled due to train faults (but no detail)

Apologies; attention to detail failure on my part.

1L82 was 802103, failed at Pilning with Air Leak. Temporary repair made, but only sufficient to limp forward to Bristol PW, detrain and onto Stoke Gifford.

1L86 was 800011/012 failed at Cardiff with DRA fault (cab safety-system) - 10 car ran empty to Stoke Gifford as not allowed to run in passenger service with safety system isolated.

As a point on the side to this incident (deer strike by an HST) , 1C91 1733 Paddington to Paignton had to start at Westbury worked by 143618 which ran ECS from Exeter.

DRA was not lit, it was still operational, had it been on ATP fitted lines it could have carried on.

The air leak was a permanent fix, no limping involved, but in these risk averse days, it was taken out - probably the decision I’d have made.

I’m not in front of the SMS so I can’t check; but off the top of my head I don’t think there’s an ATP lines derogation for DRA - what protection would ATP afford?

There is a derogation to allow the train to continue if a second driver, with route knowledge for the route being driven on, can be provided; and that was explored but not possible within a reasonable timeframe.

EDIT - take it back there is an ATP derogation...

Checking RTT, it didn't do too badly with timekeeping either - It arrived only 9 minutes late into Exeter St David's from Westbury.

Another brand new 802 with an air leak?
I'm curious how that was permanently resolved away from the depot too...
