Coach J Seat 39
I’m currently on 1M16 on 221104 and the engine on the coach I’m in (coach G) just suddenly stopped running whilst passing polmadie depot, it’s not started since, I can hear the engine running in the other coaches and we’re running to time. Is this common practice? I didn’t know it was possible to stop the engine on just one coach of a 221 whilst in motion.

Enjoy the silence!

It's probably shut itself down for some technical reason, it used to happen often enough on the 222s I drove

Also just to add- I believe 221s need a set number of engines to be running in order for the tilt to function, (I can't remember if the minimum is 3 or 4 per set) so hopefully you don't lose too many more engines during the journey. :P

I have experienced this a few times. It feels rather different when you can’t hear or feel the engine vibration.

As Bald Rick said, enjoy the ride free from Cummins clamour from under the carpet.

Voyager type trains are designed to energy exchange between cars. All cars have the engine and alternator sets but the driving cars don't have air compressors . Even so a driving cab car can still supply power to an inner car.

And as for the keeping to time, Voyagers are incredibly overbuilt it seems. I've been on a 5 car 222 that kept to time with 2 engines out!

To be honest, in general even though I know it’s okay, if there is supposed to be a diesel running underneath the carriage I’m in and there isn’t, I can’t relax, because in other types of train that usually means something is wrong.

The four car 222s were designed to be able to keep the then existing HST timings on three engines, even then they probably still overperform slightly. Compared to the 170s they replaced it must've really been like night and day performance-wise.

Just curious.
Put it this way, HSTs on one engine were restricted from certain steep graded routes unless they had a clear run or were assisted. The same applies to Voyagers on limited engines.

An HST on one engine won't accelerate as quickly but no speed restrictions were imposed on such a set. I believe that given a long enough run something around 105-115mph is possible on one engine.

A Voyager with one engine out could probably still manage 125mph, would just take longer to get there.

I have had a Voyager (can't recall if 4 or 5 car) on XC run with an engine out. Maintained timings throughout.
Was once advised by a driver of them that the 5 cars (at least) will often run with one engine providing hotel power

The 222’s do that when there’s a technical problem come up whilst the engine is running. They still keep time on the mml with a number of engines out. When they were originally introduced in their 9 car form, Eversholt and Bombardier did a timing run out of Derby with a few engines cut out to see if it could still match hst times. It beat them by a country mile.

Probably a good idea that there is a high level of redundancy in the Voyager/Meridian units, considering the routes they work.

They did the same with the 4-car presumably around the same time with two engines out and found it would still manage the then booked 170 timings of the semi-fasts! (No surprise there :lol:)

I’m not surprised. It’s good that the unit can continue with an engine or two out.

Yes, and definitely absolutely yes, to your two statements!

Only for hotel power though. Traction power is completely isolated per-car (which is one of the reasons why Project Thor, the bimode conversion by way of inserting pantograph and transformer cars, never made it to production).

Possibly, but they do run short-distance stopping services where the rapid acceleration is useful and electric mode would make them more efficient than 185s on some routes.


Yes, though I'm not sure if they have been downrated as with the 22x
XC voyager engines are down rated from 750hp to 700hp.

It's my understanding that as new the 222s could attain 110mph about 90 seconds quicker than a 170 would attain just 100mph!

XC voyager engines are down rated from 750hp to 700hp.
As are Avanti 221s and EMR 222s, they were all downrated at a similar time I believe, but it's TPE 185s I have no idea on. Would possibly save some fuel but maybe Eco Mode works better for them than engine downrating?

Happens on 158 and 159 units as well...usually get engine stop light illuminating (in the cab) then ask the guard which coach has lost its coach lights or is using emergency coach lights.

I had this on a 2 x 153 on a Birmingham to Herford service. The front 153 was in effect a loco for the rear 153. Eventually restarted at next station.
