How the Underground works records the "Hump" profile on the trunk section of the Central line of 1 in 60 out and into stations and on the southern end of the Northern line 1 in 30. The "saw tooth" gives 1 in 30 out of a station with a gradual rise to the next station. It was intended for the Victoria line but space limitations limited it's use.

The reason I thought was to give a bigger survivability because of the low clearance of tube stock as opposed to surface stock. Wasn't the Victoria line designed with deeper but only half the width of the old pits and being only on the side nearest the platform.

I only worked the District and Picc with a short spell at Leicester Square and the worst for me which might surprise people was Aldgate East. Being just above the tracks the booking halls was always full of tunnel dust and when you blew your nose the hankie was black. The ventellation fans vented into the tunnel so were constantly recycling the dust as the filters soon became blocked. I go back along way and when the steam locomotives of the engineers trains were held at the signal it was even worse. Mile End suffered to a smaller extent.

Surely congestion at Liverpool St and Paddington will be reduced with only the passengers who want those stations getting off, and with extra platform capacity at Liv St and Padd because the trains are diverted underground should allow extra trains from Enfield and Chingford. I can see Stratford becoming a bottleneck when all the tracks six to four converge plus freight movements.

In the sixties/seventies the District line in the suburbs was 12 minutes frequency. In the nineties when a 5 min service to Upminster was introduced the service actually got worse with waits of up to 20 minutes or more because the layover time at Upminster was so short late running trains were reversed early sometimes using Dagenham bay and the eastbound at the same time or more often put into Barking sidings to pick up their westbound time. Passengers waiting at Elm Park to Upminster would see trains going east never to return because they were depot to depot trains usually numbered 100, 101, etc.

As said before the tube uses all sorts of voltages such as 630 dc for traction current soon to be 750 dc I believe. Lifts were fed from the traction current substations, not sure now. Ticket machines were 110v ac. What amused me at stations which were 240v ac was we had edison screw light bulbs so you could not take them home and the three pin sockets had the earth pin turned so you could not use a normal three pin plug from home. That has all changed.

As these trains are supposed to be delivered ready to run. It should turn up very soon.

It was reported they would try to put them on the H&C line before the Olympics to serve West Ham station. A gateway station to the Greenaway (sewer bank to the locals).

This foot bridge has seen public service a number of times in the last few years when the underground has been suspended between Barking and points west and West Ham were at home. supporters were directed this way and signs were posted on the platform which often remained in place into the next week. When the track replacement was in full swing it always seem to fall on a West Ham home match.

A picc train on the district does seem to have got knickers in a twist. I hope it is not a sign of intransigence but a a precurser of flexibility of drivers. With S stock I would like to see some flexibility of a train that could go on the Uxbridge route or a H&C extended from Barking to Upminster or a circle going to wimbledon if the service needs it.

i thought the stairs and side gate from the eastbound at Leyton was for football traffic even though i never seen it used.

I am sure when these trains were ordered it was with provision for a trailer car and the platforms were only refurbished for three cars.

Barking sidings which is fully signalled by shunt signals but passengers are still not allowed through during engineering works and are made to bus to Upney to pick up an eastbound train that has reversed at Barking and passed through the sidings. And I am sure they still have staff to detrain passengers for trains going out of service on the eastbound. Incidently because the reception road is so long trains can enter the siding at line speed.

If it was the underground it would be because passengers cannot travel past a shunt signal because technically the route is only locked by a colour light signal. The DLR is generally bi-diirectional I think so they probably have different rules.

With S stock and the new signalling the opportunity is there to reinstate the District to Uxbridge and send the Piccadilly line to Ealing Broadway.

I always thought traction current was the best terminology as it is the power that gives the train movement as apposed to signal current. I never liked the word "juice".

I thought I had better revive this post to see if a special service could be provided as West Ham have got to Wembley. There is no engineering works on the District or Met on the 19th May

When I was a boy I can remember the diesel freight trains thundering through Wapping between the Eastern Region and Southern but I excpect they were not doing more than 30mph. With it now London Overground I would think freight could run even if only as an emergency route.

Now there is an even chance West Ham FC could be at Wembley on the 19th May, have the planners been working on any specials. I would love to see an S8 but I expect they will tell supporters to travel via West Ham and the Jubilee Line.

I seem to remember there was an inner zone and an outer zone. The Inner ticket had two vertical green stripes towards the middle and the outer had green stripes at each end. Then the composite fares to upminster and i think to Amersham and maybe Epping as well.

As West Ham FC might be at Wembley this season on May 19th, will we see a special service as in the "old days"? What stock would be used? Or as more likely "modern technology" will not be able to cope for safety reasons.

Surely the platforms being demolished at Blackfriars are the old terminal platforms and the old through platforms of Network rail.

One of the reasons i left the underground because for example I would arrive at 7am to find no night turn, collect the keys from the next station then at 3pm no late turn to take me off so take the keys to the next station. When on nights I would have to go and lock up the next station and reopen it the next morning. If you did not have a car the managers would get a taxi for you. In my time we worked alone selling tickets, going to the platform, down the track if required. It was ironic we could go on the track in traffic hours but not in non traffic hours. I am not talking about 30 years ago but 10 years ago. I can't beleive it's much different now.
