Hail All! <D
Well, there's a few right and wrong answers here so far...Although some are obvious, and others less so. Here's the read-up thus far: :)
  • Class: 370 APT (Class313 mentioned it off-hand, but I'll accept it. :))
  • Sub-class: APT-P (LaSeandre first to mention. Not really important, but didn't the APT-E also have 370 as her class number?)
  • Location: Railway Age, Crewe (Emunit got it...But where else can ye find an APT-P nowadays? :lol:),
  • Parts: There are two (Maybe three) distinctive groups of components visible there, but neither are part of the actual tilting system. :)
    - First component group: The perforated steel structure, used in certain emergency applications,
    - Second component group: Parts linked to the steel disc with the BREL logo on it.
  • Location in rake: It's not located under either of the driving (DTS) cars. The second component group is your biggest clue as to the location! ;)
Also, here's another few questions to test your knowlege of the Golden Age (In my opinion) of BR's train research and development. I want ye to try and answer these off the top of your head though...And therefore Googling or using other search engines or referance material including books etc. is to be considered cheating! :shock::lol:8-)
  • Question 1: Although the APT-P was designed to be a fully tilting train, one component of the train had to be kept "stable". Which component was it?
  • Question 2: The Spirit, speed and design of the APT-P lives on in one particular type of long distance train that is still extensively used to this day. Which train is it?
  • Question 3: Considering the train that is the answer to question 2; There is a design difference between it and the APT-P that can be adjusted to make the train functionally identical to an APT-P set. What is this difference?

Yikes...That were quick! <D
Nym's done well there (Ye didn't Google it, did ye? ;)) and got the first two questions right! :D
The third one might be a valid answer (I assume thy answer refers to how the pantograph can be mounted? I'm not good with big words! :?) but it's not the one that I'm looking for, sorry! :)

A clue for question three is:
Although it's a relatively simple modification that has been taken into consideration when the train was originally designed, it would require a well equipped workshop, additional parts, and a good couple of days (Minimum) to actually perform the modification itself to a trainset. :shock:
As far as I know, this modification has not yet been made to any such trainsets, but I'd imagine that it would still be possible and relatively easy for a workshop with sufficient hoisting facilities to do. 8-)

Farewell... <D

No, I didn't google it...

I knew about the IC225 from reading ages ago, and I made an educated guess on panto stabalisation, at it interacts with the outside world, and having looked at the mountings on a 390, the're incredibly complex. Like I always say, IEEE/IET in training ;) Electromechanical Engineer (Mechatronic, E&EE) in training, hehehe

Btw. Are we talking modifications to the 91/0 or 91/1 locos?

Well, we're actually talking about modifications to most of the trainset itself, although I do seem to recall that the locomotive would be the only part of the train that wouldn't receive this modification...So the loco class/sub-class is pretty much irrelevant in this case. :)

Now what kind of modification might be applied to a train, but not it's power-car? What might such a modification be in aid of? ;)

Well, on the Mk4s you'd need to fit articulating bogies, new doors (for safety regs), and a new type of gangway system, (depending on how they tilted).

Cant readers, wheel accelerometers etc. would also come in handy...

Hmmm...From what I recall from reading about the IC-225 a while ago, the passenger car bogies were all designed so that the APT's tilting system could be fitted to them relatively easily and without much more work aside from lifting the body, removing the existing fixed steel "post" that supported the carriage, and fitting the APT tilting cradle (With all necessary detection/analysis equipment pre-fitted) in it's place! :)
Mayhap the additional requirements (New doors etc.) are something to do with new safety regs bought in after the IC-225 was designed? :?

And what do ye mean by "a new gangway system"? From what I can recall of taking a peek at the APT-P last year, the gangways were identical to any other type of train from what I could see, and the only unusual feature there were the diagonally offset passenger doors, which I always thought were a cost-reduction measure on BR's part! :)

yep, they where, IIRC the pindo and vomiter doors have double cross locks on them and can take somthing like a 150tonne impact...

And the 91/1s would need a full refit as all tiltey stuff was taken out and scraped

on the subject of other ATP's locomotion have the original gas turbine version and one ATP power car is there any other examples i dont know about.

AFAIK the 91s were never fitted with tilt in the first place, it was the tilt system's installment points that were removed when they were put through their mid-life refurbishment programme.

The cl91 had the space reserved for the tilting equipment used for the wifi equipment when GNER fitted it, since there was very little chance of them having tilt fitted unless they end up on the WCML when the IEP comes along. Whetehr this would be to supplement the Pendo fleet, or to add capacity to the LM routes would be open to debate. They could even end up on the GEM, although their acceleration is poorer than a cl90.....and GEML is getting long EMU's soon according to the RUS. It will be a shame to see a good 20yr old fleet getting binned otherwise.
