That 'Hunting" in idle is when the electric train heat was used. I believe the idle RPMs was 620, instead of the normal 450, the former being the equivalent to notches 4 and 5.

Thanks

Thanks for the explanation. It certainly is distinctive...https://youtu.be/N28Ea4Q22GY?t=6m43s

Pity its not the slim Hastings version, it could then be used on the Wherry lines running backwards and forwards between Yarmouth and Norwich as in Anglia railways days,

Arguably there's more scope for a 205 with the London - Brighton and South London Network covering a number of mainline duties.
Plus the number of preserved railway lines that have featured 205s and other thumpers like the Lavender Line, Watercress and Epping Ongar for example, that are available to us.

You'd get the best use out of a 201 I feel if you had the Hastings - Tunbridge Wells line to go with it.

Hi
I was just wondering what the difference is between the 205 and 3 Hampshire units are,as I was thinking of using them on the Watercress Line by JT and the new SSS Southampton-Bournemouth Route's

Well they're all the same essentially, albeit most in preservation are missing the centre trailer coach.
205205 is the exception as that was prototypically modified with gangways , false ceiling, fluorescent lighting, PA system and a redesigned seating layout. However, AP have said they will not be reproducing these modifications for 205205 at the present time.

But that was a one off railtour - a bit pointless if it's selling feature is "you can use it on a special"

Anglia Railways did hire the class 201 for a few months to work on the Wherry lines as cover I believe.

However I agree, I would much rather see the class 205 rather than the class 201 unless the Hastings line was released with it!

Being EE they hunt anyway, quite often, every time I have seen 1317 at the Spa Valley regardless of the time of year (and therefore use of heating) it has hunted. I spent the day on it driving with a friend in late summer last year, it was absolutely boiling, no heating on (no passengers to be heated anyway!) and it hunted basically the entire time it was at notch 1 or idle.

Well looks good but I would just like to point out and thank jordi for this as it is him who is making it and hosting it on AP. Just like his amazing class 319 and 456 so thank you jordi as always another perfect example of a developer making us great content

I'm not saying it will not hunt at 450 rpm. At 620 rpm with no load, the hunt is more pronounced. And you cannot really compare one unit, as in their heyday they idling sound varied from one unit to the next. I certainly remember the idling sound with no pre-heat(450 rpm) was more in-tuned and ticked over uniformly.

Another thing was these units were underpowered. The engine 'unloads' around 55 mph. I doubt if any DEMU on a preserved railway will encounter even the first field divert.

Back to TS, wouldnt mind seeing these units on a route to East grinstead or Uckfield.

Thanks

Sounds very much like your having a pop at AP (as usual).

Don't forget the work that others have put into those release too (321 not 319), such as AP and Waggonz etc.

Good point, well made.

I absolutely adore these things, so am very much looking forward to them... and no one better to make them! The only way this could get better is if they do the 207s as well.....

the people u need to ask about the old selhurst survivors are the front seaters from SU & BI who actually operated em, each one was different, like an old minis each had their own personality, they were built and maintained by people and have a soul..unlike the autonomous machines that have replaced them, their personalities eradicated by computing power ..
