I'm thinking of a train class..

[Ivo]

Nope. Still some distance (not literally!) from the correct answer.

 

[Class172]

Class 458??

 

[Ivo]

It's not a 4xx or a 5xx.

This unit does not have a 3-digit TOPS code.

 

[Class172]

Class 73?

 

[Ivo]

Nope. It is a Multiple Unit.

 

[Class172]

Does not have a 3 digit tops code yet is a multiple unit. :?

 

[Ivo]

Aye. There is a trick here. Let me remind you that the unit this class indirectly replaced can still be found south of the M4, in spite of its age.

 

[gg1]

London Underground 1972 stock?

 

[Ivo]

You've got the right idea, but not correct. You couldn't be much closer.

 

[gg1]

Yay

1973 stock then?

 

[Ivo]

That's colder.

 

[gg1]

1967 stock?

 

[Ivo]

Keep trying. There is a small note in the original clue that you appear to be overlooking.

Too subtle a clue for me I'm afraid

1962 stock?

 

[Ivo]

You're heading the wrong way. Come nearer the present.

LU 1983 Stock

Replaced 72 stock, still used on the Bakerloo...

And none have been scrapped, all sat in depots... or as an artist's workshop, etc.

 

[gg1]

1986 stock?

 

[Ivo]

Bad news for our roving rangers Class172 and gg1:

LU 1983 Stock

Replaced 72 stock, still used on the Bakerloo...

And none have been scrapped, all sat in depots... or as an artist's workshop, etc.

This is correct. If you think about the clues exactly as written, you could also argue that the 1972 stock was itself a replacement for the 1938 stock (making the 1983 stock its indirect replacement given they coincided; this was the trick element to the clue) - which is still found on the Island Line.

The unusual feature was the single-leaf door, which is still in use on D stock units. And of course the route upgrade was the Jubilee Line Extension to Stratford.

 

[Nym]

Thankyou muchly...

I used (and still use, in most of me) the same type of traction equipment as the last train class to be built at a factory within 100 miles of where I sit now (Bolton, Lancs) but am now having this changed for a different traction system made by a company that is contrivertal at the moment with one of their UK rail projects.

If that is too hard, let me know and you can have some more clues.

 

[150222]

I'm stumped!

 

[Peter Mugridge]

Networker 465; having their traction equipment replaced by the Hitachi version, the controvery being the IEP?


Open floor.


( PS About half the 1983 stock was scrapped wasn't it? )

 

[Nym]

Anyone else, I don't think this is that hard...

Last thing to be built at a factory within 100mi of Bolton, same type of drive system as something else that is having it's drive system changed, want to know the one that is having it changed.

Correct, the unit being built near me the 323, networkers also using GTO Thyistor drives at relatively low switching frequencies.

And I'll take it again...

I'm a 'newer' version of stock basically the same in use on a different line with two branches, my line has no branches and the stock in use on my line that I am has recently had a carriage added, we both operate in the same passenger transport executive. My stock replaced some not very old stock that was classed as not very suitable, it also uses the same drive system as the last peice of stock.

(This should take you about 30seconds the amount of clues there...!)

 

[Peter Mugridge]

Sounds like the S stock, being a newer version of the class 378 design?

Except for the branches bit.....??

Open floor if it is anyway.

 

[Nym]

Nope, is a bit older than that...

Also note the '' around the newer, it's a newer designation, but not essentially a newer design. And remember it replaced stock not that much older.

 

[Class172]

Class 171?

Open floor if correct.

 

[Nym]

Not a 171, I operate entirely inside one Passenger Transport Executive
--- old post above --- --- new post below ---
I'll add another clue for you, this type of unit has never carried a TOPS number.

 

[Schnellzug]

The Manchester Metrotrams?

 

[Nym]

Nope, the unit has a newer classification than it's sister, but uses an older design.

Remember, uses the same kind of drive system as my previous 'thinking of'

 

[150222]

Tyne + wear metro trains?

 

[Nym]

No... What are T&W Metro Units related to?

Discount the PTE thing and you will proberbly get warmer...
