There were detail differences in the performance of each train, but for operation the software that controlled the propuslsion packages was set so they all performed the same. We tried, and usually failed to keep 2 6-car trains available for service with one 2-car from each train. The blue train was not allowed to run other than as a two car set as part of a 6-car due to worries about the fade characteristics of the motor mounted disc brakes.

ALL tripcocks on LU are pneumatic. Even though they've gone, '92ts tripcocks were no exception

Under a panel at the at the end of each unit are basic driving controls. The Customer Services person is trained to drive in an emergency. There are no signals. Movement authority is given via the display on the driving controls - not certain exactly how, but something like a second needle on the speedometer

Tubeprune; Thanks - the offset transom bogies were inferred in Steam to Silver, but not positively confirmed and although I recall travelling on them (after I started work!) I didn't recall absolutely for certain.

My "bible" - Steam to Silver implies that the 25 Q stock motor cars had the same bogies as the O and P stock - thus one motor per bogie; but it probably needs Tubeprune to confirm

And make it very clear on the trouble card that it's "weak brakes when loaded". Then they can't just clear in a depot test run and they would need to check the variable load system.

I had a very scary moment when I saw this thread; a C stock and 72ts would be a REALLY unusual formation

Steel and Aluminium trains would have been set to perform the same as they could couple to each other. Any differences would have been inconsequential

And braking would have been marginally better than COP stock.

Tubeprune has probably driven them and can no doubt provide first hand experience!!
As far as I recall, the electrics were set and they were geared to have a high (for the time) initial acceleration and low top speed. If you have already got COP stock, I would give it a slightly higher acceleration and slightly lower top speed. Top speed will only matter on the east end of the District and the Wimbledon/Richamond branches.
I recall that drivers would hack round the curve into Victoria EB much more quickly than they do today! Probably something to do with the absense of an efective speedometer (on the old train, that is!)

as to why they were withdrawn:
they were less reliable than the old locos and, crucially, not as powerful as locomotives

The operating mechanism is under the seat and operates the door via an arm that's connected to a shaft that goes through the bodyside. As there's a pillar either side of the doorway to restore the strength lost by cutting a ruddy great hole in it (the doorway!), the shaft has to be some way back from the edge of the doorway. When the design was first developed we decided to cover the external arm. This design had been used elswhere (eg Boston) and the arm had not been covered. It was seeing that design that persuaded us that it needed to be covered!

In the unlikely event that '92ts ever went near the ECML it might be a clash, but NR assign a special class code to any trains that work on NR - currently only C, D and '72 stocks

50th train has been received by Derby. Whole thing due for completion end March 2008 - more or less on time.

Is it the memberships' collective aim to get this thread to 75 pages by the time the last of the 75 trains is refurbished?

if you're on a District, Picc, Central, Jubilee or Northern train you could use the talkback to try and find out what the trouble is whilst waiting at the signal.

I had the naive view that the PEA alarm was very distinctive and different from all the others? ??

Post by 100andthirty on Mar 21, 2008 16:44:06 GMT
The rule is simple: if departing a station and a PEA is operated, then stop (subject to station limit markers etc). OTHERWISE over-ride the PEA and carry on the the next station.
if the PEA is operated on the approach to a station and the train stops before the train op. can react, release the brake and draw up straight away. Sound the whistle if at all concerned. This is common sense. The people waiting on the platform don't generally lean on the train when it stops and PEAs coming into stations are rare; both together would be very very rare.

the right hand driving position was adopted because the Train Op's main focus will be on the platforms and most of the platforms are on the right. This decision was taken before any decision about mirrors/monitors whether in cab or external.
in the end the in cab OPO CCTV solution was chosen so that all shapes and sizes of Train Op can see the images clearly

It's tradition!
but the new Victoria Line trains have the driving position on the right.

It is now 2007. Two lines are automatic; the train operator is just a machine minder/door operator. Jubilee goes over to this in 2009; then Northern, then Metropolitan, Circle, H&C, District and Picc. Then by end of next decade, Bakerloo. All based on current plans. You should bear this in mind if you want to drive in the long term.
