Hasn't happened yet though, to my knowledge at least.
It was being discussed in the Messroom at EX the other day and nobody could think of an occasion when 150/1+ anything had been to Exmouth.
But when there are 17 on the fleet it'll happen
I've been to Exmouth with a 150/1 + 153. I think on that occasion the 153 was leading going towards Exmouth though. I believe the local staff reps are going to ensure a method of working is agreed prior to introduction of the other 15 150/1's. They will have plenty of time I understand the 172 project has had another set back in the form of serious back pressure issues in the Exhaust system. May 2011 is now being mentioned....... |

No, that was some time ago, which meant Electrostar production ground to a halt at Derby, which in turn meant they were late setting up the production line for 172s. |

I'm trying to get my head round the issues with the 172 order. 170 and 171 units are a well-established and successful design. Were significant design changes made to the 172s, and if so why on earth would that be done?! Why couldn't LOROL▸ et al have ordered 170/171 stock that would have worked "straight out of the box"?

The lightweight bogies (like 220s) required the exhaust to be completely re routed - there are apparently problems with exhaust gas affecting the aircon somehow. I'm not sure but the engines may be a newer type to meet current emissions regulations, and the gearbox is mechanical, rather than hydraulic as in the 170/171.

class 170/171 trains are popular and work well but they are not prefect. Compared to a 158 they are heavy and therefore less efficient and attract a higher track access charge. IIUIC, the class 172 is an attempt to mitigate those problems.

I think they will be hard pressed to manufacture a modern train that is sufficiently lightweight compared to the sprinters as there is so much modern junk which needs to be fitted to tick a box for a Bureaucrat sat somewhere in Belgium!

well 121 interior certainly looks better although i notice same floor covering and seating (bar new covers)
so i suspect there will still be a problem with them coming loose.time will tell.
when they get full refresh lets hope the above gets addressed

Not quite correct. Close but no cigar.  The exhaust (which as has been mentioned has to be rerouted round the bogie rather than over the top of it due to lack of clearance) is apparently somewhat restrictive and causing too much back pressure at the turbocharger turbine outlet. It will be noted that pressure difference and heat energy is what drives the turbocharger turbine wheel so creating a large restriction downwind of the turbocharger is not a particularly good idea. There is a lack of performance with the sets as a result, depending on who you talk to depends on how slow they are said to be. The ZF Ecomat 6 speed transmission is not thought to be causing any problems. |

They've been there for years, hence the set stinks when you board it first thing in the morning....... |

Sorry folks - those pix were taken on the depot and so weren't intended for such a wide distribution (they were being shared with other staff, and I should have password protected them sooner). I'm sure someone will be along to take some shots of it in service in due course.
As for the BR1 key sticker, it cost nothing to get it included in the label pack and looks a damn sight better than "Don't forget your BR1 Key" scrawled in black marker pen!
To set the record straight, the work on 121 comprised simply:-
- Internal repaint
- Renewal of all seat cushions plus covers (not just new covers)
- Heavy Clean
As others have already alluded, the intention is to cycle these two units through again when the remainder of the 150/1s go through refresh.
As for 150127, expect more of the same as 121 got, including it's release with the current external paint job. Nothing yet in the scope for repainting the outside!

Thanks very much for that useful insight, d5351 - and a warm welcome to the Coffee Shop forum! Chris.  |

William Huskisson MP▸ was the first person to be killed by a train while crossing the tracks, in 1830. Many more have died in the same way since then. Don't take a chance: stop, look, listen.
