Dapol Class 121 and 122 in OO gauge

Would a class 101 soundfile be suitable for a 122?

By memory they sounded different, perhaps because of the exhausts being on the end? I did usually have them as single cars.

 

Legomanbiffo does do a single car sound chip.

All five standard release Class 122s now showing as 'in stock' at Hattons and I've had an e-mail to advise my pre-order has been processed. My 122 driving trailer conversion is completed on the body conversion, waiting painting, but will check the colour match as Chris Leigh (Model Rail) has advised that one of the green versions is the correct early BR lighter green applied to some dmus. The photos showing are still the pre production ones and are probably incorrect body styles for some versions. Hattons should have their photos of the delivered models in a day or two.

Yes, check your match with the actual model. I was presented with three different colour swatch books which represented all the paint shades available to the manufacturer. We chose the one which was the closest match to my Lima 122 conversion which is painted with Railmatch early DMU green. However it was painted about 30 years ago and there's no guarantee that - 1) The paint we chose is a perfect match to the swatch. 2) That today's Railmatch early DMU green is the same as it was 30 years ago. 3) That your eyesight and mine see things the same. The original DMU green both weathered and faded very quickly, and virtually no two cars were the same colour for very long - which is a perfect excuse for slight mis-matches! (CJL)

I'd agree with dibber on matching colours; close enough for jazz is fine, and a small difference is not a bad thing.  Lightly weather the lighter shaded vehicle, whichever one it is.  Dmus generally matched within sets, but not with any presision between sets, and of course might mis-match completely during times of livery change, i.e. light to dark green for your period.

Principally they are the same, but single cars tend to rasp a lot more as the silencer setup is different or non existant on a single car, where as 101s have the large silencers just below the exhaust.

From the pictures on the Hatton's website, I'm happy to say that they've got the livery colours correct for the RR, blue and blue/grey ones, including a good warning yellow (I'm not commenting on the green ones only due to lack of knowledge on my part!).

Postman just delivered my class 121 from Hattons. First impressions are a lovely model very heavy colours look right to my eyes. Very nice detailing, there is a bag with all the pipes for the front end as well. Not able to test run it just now as the layout isn't quite ready. But loving this model. Another winner for Dapol

Stuck in the tunnel at Blaenrhondda ? :jester:

 

Don't be silly. The Severn Tunnel of course! Although if they making their way down from North Wales to South Wales probably not. They're probably on shed somewhere. :yes:

The blue one looks great.

Can anyone advise as to the wheels and pick up arrangement, i will need to EM mine, will it need new wheelsets or will a bit of pulling them out do the job?

 

I haven't taken off a keeper plate, so this is from examining the wheel/bogie system with magnifying modelling glasses. There are no sprung pickups on to the backs of the wheels, the electrical connections are flat against the inner bogie frame and connect to the axle bearings, so the pick up system seems to be via live bearings. The wheelsets have no insulation that I can see on either side of the wheelset, which supports the use of live bearings, so the wheelsets must be stub axles with a central insulated section/final gear.

Split axle, the axles look to have enough meat on to pull the wheels out, plus it rather looks like there is no need for any plastic butchery for clearance.On the negative side the wheels are a bit wider than should be and it may be a case of proceeding as I did with my Heljan DPU, making the BTB a midges dick less than 16.5mm, which worked a treat when wheel pulling.

I'm feeling a bit concerned about the pick ups. With that arrangement, it might be, that for good and consistent running, that the same modifications that were needed with the first batch of Bachmann class 40's may be needed with these units. Time will tell as more are purchased, and any running issues arise. I hope that modifications, by adding wiper pick ups, will not be needed for reliable running.

 

Regards,

 

Rob.

Been having some fun 'tweaking' the Class 122. So far, I've repainted the floor, fitted passengers and drivers (both ends), made my own destination blinds. The supplied blinds reflect the view of the person who wrote the instructions - that the 122s were mainly on the Midland and Scottish Regions. That ignores their first five or six years on the Western, of course. The supplied sheet includes some for Tyseley cars but misses such major stamping grounds as St.Ives, Seaton, Lyme Regis, Bude, Padstow, Bodmin/Wadebridge, in the west country and notably Much Wenlock, and Bromyard in the West Midlands, as well as all the London area branches that had 122s between 1958-60. Included are Bromsgrove and several other intermediate stations that are unlikely to have seen a Class 122 on a terminating service, while Moreton-in-Marsh (which did see such a terminating service) is incorrectly spelled. I've repainted the exhausts and axlebox covers, and the roof domes. The latter are supplied white (as delivered from Gloucester RC&W) but they quickly weathered to a creamy colour and that's how I remember them. To my eye, it looks much better painted to match my memory. CJL)

This is a normal method used on umpteen US diesel loco chassis. I don't know of any that have needed wiper pick-ups added to make them run reliably. Certainly, I've been running this style of chassis for at least 30 years without problems. (CJL)
