Make up your minds about the smoke atleast
Edward

The amount and colour of smoke being produced is indicative of the condition and use of that particular single locomotive engine rather than it being the trait of a particular class.

A well serviced, tuned and optimised engine running at design temperature and throttled sensibly will not produce much smoke whatever class of loco it is fitted to. An engine that is not running in this ideal state will be a clag-monster!

You see the same effect with diesel cars/vans. You could take 2 seemingly identical VW Transporters and depending on how well the engines are tuned, balanced and serviced, as well as the style of driving, then one could disappear in a cloud of smoke and the other you wouldn't even know the engine was running!!

Correct, for example take 37905 and 37906 they both have the same engine type used.... However 37906 smokes alot more with thick black smoke that seems to suggest unburnt fuel it getting combusted in the exhaust chamber instead of the combustion chamber whilst 37905 smoke alot less....

Now isn't this type of argueing where the Romans invented their 'forums' for. Remember this is a forum too ...

The 50 does actually pay attention to temperature, but I can't remember if that got used in the smoke - I suspect it didn't. It certainly is possible to log engine hours/time idle/average running time etc for each engine.

Actually controlling the smoke is another matter without festooning it with hundreds of emitters...

Bought mine direct from Meshtools so I haven't got the 2012 on fire effects

Having spent many hours travelling on and watching 50's at Plymouth in the 80's they, like all diesels make exhaust smoke. The video made me feel sad.
Most (white) smoking is caused by a cold engine - not up to running temperature, and especially a cold worn engine. The smoke and is systematic of both.
When in regular revenue earning service the engines would be working hard over long hours. Once running temperatures are reached the engine would smoke a lot less and be more thermally efficient. Engine wear would be reduced as long as correct lubrication was maintained with regularly servicing.
Whilst it might be spectacular to see a 50 making lots of smoke and see people hanging out of carriages enjoying the noise, smell and sight. I would rather remember them as hard working 100mph capable locomotives carrying me and many others down to the West Country..

ps: Anyone else remeber watching Deltics pull away and seeing the twin plumes? and the sound and... sigh..

Everyone who was on the 5 deltic beerex last year was smoked out by all 5 powering up in the tunnel... Was speaking to one of my friends who was in the rear cab of 9016 for the run and he said that the got that full of smoke he was coughing... Plus the smoke didn't clear for a good 10 minutes after leaving the tunnels...

Don't forget idling engines tend to build up crud in the exhaust, which gets blown out the next time it throttles up again.

I'd be quite happy to spend an extra 20 mins getting to London if I could do it in an aircon Mk2 again. 50 power to Waterloo wasn't quite so comfortable...

I'd much rather travel in an air-con Mk2 than a pendolino being dragged by a 57, seeing as the aircon units on the pendos are on the roof meaning one exhaust on the 57/3s had to be blocked to stop the air con being filled with the exhaust gunk...
