OT and then some: railway engine racing?

HSTs have leccy motors.

 

heh. The hole digging on this one is approaching Lozzo-esque JCB
levels.

Poor Grimly - he's normal so careful too [/QUOTE]

I'm sure you, I and sweller know exactly what Grimly means but the
"ukrm way" means this sub-thread will probably go on for a bit longer
yet!

So that's what they call 'em. Your posts are IMHO among the most
informative on UKRM.

Oh look .. a little applet ..

Long may this transport strike continue.

Tum tee-tum ..

It was well reported at the time in the tech journals and I believe it
was the train with lots of teething troubles which, given enough time,
would all have been ironed out, but was consigned to the sidings of time
because of cost overruns and political hoohah. Prolly the APT, but maybe
not. At the time there was a desire to catch up and outpace the French
TGV and the Japanese Bullet Train.

Whole problem with the pantograph was the destructive result it had on
the overhead lines and the aforesaid trouble with the standing wave
causing a carriage roof strike - as I said, it was not foreseen at the
time and caused a hasty re-appraisal of just what could be done on
existing lines [1]. If you recall, the whole point of the APT (if such
it was) was that it could be run at high speeds on fairly normal lines
(hence the tilting bit) but it turned out that other parts of the line
structure needed to be seriously looked at too.

[1] Was that not why the power car ended up being in the middle of the
train? Effectively dividing it into two trains and no connecting
corridor?

The Bullet Train in 1964 and the APT project in 1966 (it has its roots
even earlier than that). The French TGS prototypes started in the late
sixties, the TGV itself started in 1981.

Both the Japanese and French used new infrastructure for their high speed
lines which BR couldn't justify so the tilt mechanism was used to combat
the problem of the winding WCML.

The wave effect you describe is not due to any experimental train but too
higher speeds on traditional simple cantenary overhead line equipment
(OHLE) - the wires are the problem not the train.

No. They were motor coaches and the traction motors weren't bogie
mounted but in the carriage. Why it had no passenger through corridor I
don't know but the position of the pantograph has no bearing.

 

Meant to ask - which ones?

 

Fukd if I know - it was 30 years ago.
