150 and 172 paired up

[monty9120]

decided to take a run out on my scoot to worcester. about 6.15 yesterday evening i saw a 172 going over a bridge with a 150 on the back.

any idea which ones these were and whether this is a normal occurance

 

[fgwrich]

Crikey, well that's one way of doing in the 150 then (The 153s seem to spend most of there time reving there nuts off when paired to 172s - Surely it must have some impact on the Sprinters?!)...

Thought it was only 170's that had the ability to couple to 15x's? Or are 172's fitted with this technology too?

They are both completely* compatible with 15xs.

* - 156s require a mod to work with either; corridors are not compatible due to differing width.

Hmm... I've never seen that, hopefully we can see more of this, especially on the Snow Hill Lines

The Combined Volume lists classes 150, 153, 155, 156, 158, 159, 165, 166 and 170 as able to work in multiple with class 172.

I have also wondered, has a 165/166 ever worked in Multiple with a 15x unit, as when the Turbo's hopefully go west, we could see Turbo Units coupled to 150/153/158's ?

Thanks for the info: WillPS and Peter Mugridge

I don't think Turbos/168s are compatible with Sprinters, but don't quote me on it. I can't remember where I found this. Would there be any point without gangways?

Hi
150s will work with 172s, as 153 did for a short while from B'ham Snow Hill to Stourbidge Line!

But you have to remember as the 150/153 is a fluid auto gearbox much like a car the 172 is a machanical gearbox although it changes up/down by engine rpm!

When this was used with a 153 on the Dorridge turn there was a lot of pushing and pulling goin on!

I have often seen 150s and 172s late at nite on ECS back to Tyseley in the past before they all left for pastures new and far!

I still don't understand why a 168 and a 170 couldn't work together :?

Software I believe, or maybe the pin arrangement on the electrical connection block under the mechanical coupler.

Tempted to wonder if the 17x series - being descended from 165/166 design - are inherently compatible with Turbos, and were also designed to be compatible with Sprinters

.. which wouldnt mean a Turbo and a Sprinter could work in multiple, unless they had a 17x in between

When the 165s and 6s were ordered NSE wanted their units to be wired out to the couplers in a different configuration to the 14X and 15X previously built, then of course Chiltern needing to run 165/168 consists had little choice but to specify the same for the 168s.

I know the LM 172s were specified to work with 15X units, sadly the gangways between a 172 and a 153 are not compatable but the two will work in multiple so a similar situation should exist with a 156 or a 158.

I know the Chiltern 172s work with 16X, as for LOROL class 172s who knows?

I did read in a magazine many years back when the 172 was first muted, that the head of Chiltern at the time suggested switch in the cab could be provided linked to a multi contact relay thus providing the flexibility for them to operate with either 14X/15X or 16X.

 

[MCR247]

But some of the centres cars were built as part of the 170 production line :?

 

[D365]

The 168 subclasses are different in various ways due to the miniscule batches ordered, as ADTranz/Bombardier in fact supplied the 170s of the moment, but modified to Chiltern spec.

Ah okay
