Norton Wood Posted September 6, 2018 Share Posted September 6, 2018 Hi, I don't know if pictures/post has been put on here before comparing the Golden Age Models Dyno Car with the Rails Dyno Car, so I thought I'd put some pictures up comparing parts, for this I am comparing my LNER 1938 Mallard Record-breaking Dynamometer Car from Golden Age Models with the, 1948 Exchange trials Dynamometer Car from Rails of Sheffield. I'll let the pictures do the talking; "A Picture paints a thousand words and all that". 5 Link to post Share on other sites More sharing options...
amdaley Posted September 6, 2018 Share Posted September 6, 2018 (edited) I put my Mallard with the Rapido Dyno car to see how they'd look together. Edited September 6, 2018 by amdaley 7 Link to post Share on other sites More sharing options...

trevor7598 Posted September 7, 2018 Share Posted September 7, 2018 I received my V2 dynamometer car today and whilst visually it is stunning and flawless, I am having running problems with it. When going round a curve, the front bogie is consistantly derailing due to the bogie not turning to enough of an angle. I have tried it with multiple locomotives and on both second and third radius curves on my test track with the same results. Has anyone got any advice? I agree the model itself is stunning, but I too have problems with constant derailments. Yesterday I had a Hornby Bulleid pacific and five coaches running flawlessly for over an hour. As that proved there was nothing wrong with train or track, I once again tried the dynamometer car, it derailed in five places in one circuit, always the leading wheel set lifting off the rail. I have tried loosening the bogie pivot screw. to no avail. It would appear that Rapido have used very fine scale wheels with very shallow flanges, compared to Hornby or Bachmann standards, which is asking a bit much from track that is not absolutely perfect.

Even if the wheels are RP25 it should run fine. No issues with mine running anywhere on my layout even with old fashioned 80s stock I used for my pics posted here. By contrast my DJM 71 also with RP25s pops off every few yards or so - although the other day, it did manage to do 15 laps before derailing! It is always the leading pair of wheels on the leading bogie. I put this down to the rather stiff bogies with little or none down play (maybe for the 15 lap special it was finally getting looser over time or maybe room temperature adjusted all the rail gaps to be perfect for this model on that occasion....). Other(s) here have talked about screws done up so tightly that the model had a small crack and made adjusting difficult. Link to post Share on other sites More sharing options...

I refer you to my post No. 803 above. Loosening the screw is not the only solution. Check to see if the bogies will tip fore and aft as well as laterally (just like the real bogies do).This compensation allows for them to ride the variations in the track. The "play" must not be excessive, otherwise the body will wobble, but do have a look at the ends of the pivot posts to ensure they have not been spread as in my example, possibly at the hands of the same gorilla!! The little tweak performed on mine has cured it and it now runs nicely as it should. At the risk of being big headed, I can draw on a technical career covering a big chunk of my 72 years, so I have the confidence and knowhow to solve all sorts of problems. I'm more than happy to share AND learn new things along the way. Happy modelling folks Tod Link to post Share on other sites More sharing options...

I'm also rather baffled about the white roofs and dyno' wheel as depicted on both versions, as they certainly do not appear white in the contemporary period images. I have the Rapido version and I'm going to tone both of those items down to fit the 1938 photos. M. 1 Link to post Share on other sites More sharing options...

HOTTODDY Posted September 7, 2018 Share Posted September 7, 2018 much better to thoroughly investigate and rectify track irregularities. Quite so, but if the bogies are not operating correctly, then they will find somewhere to derail, even if your track is "plate glass" level. 99.99% of layouts are made of wood and that stuff will move, due to temperature and humidity. The very finescale modellers (P4 et al) have very good accurate track, BUT they also have compensation 'cos scale flanges demand it. So, it's not just one thing to look at. A process of elimination should eventually solve the problem. My own problem was the bogie pivot that was too tight, even with the screw removed. .I carefully filed off its offending swollen end (?) and hey presto, job's a good 'un. The very fact that neither the loco nor the six coaches hanging on the back of the Dynamometer car derailed. I had a pretty good idea of where look first and as others on this forum had experienced a derailment issue with this vehicle, I used that info, which I'm very grateful for and sorted mine. I'm old, tired and it's way past my bedtime. The nurses have locked the door and put the lights out.....................................................!

mvwilson Posted September 8, 2018 Share Posted September 8, 2018 Mine derailed in a couple of spots on my layout. It was the track that was the problem. Once i adjusted the track it has been fine. Link to post Share on other sites More sharing options...

Silver Sidelines Posted October 14, 2018 Share Posted October 14, 2018 "How bright are your lights?" I was asked. In daylight the interior lighting is hardly visible. However in the 'dark' the lighting works a treat and well illuminates the detailed interior.Ex LNER Dynamometer Car from Rails of Sheffield by Rapido in the dark I do find the Harry Potter Wand and the magic reed switch to be inconsistent and had thought that my Gaugemaster DS controller might be causing the confusion.

JSpencer Posted October 16, 2018 Share Posted October 16, 2018 It was a tough choice between this and the Accurascale HUOs, both complex and top of the range models in their own right. I feel the survey was unfair to to have wagons and coaches merged in one category. Comparing day to day wagons with a coaches of glamour is like comparing different types of apples with different types of oranges and choosing the best between them. But I had no doubts that Rapido were going to win this with such an excellent re-production of such an excellent prototype. Well done Rapido. Link to post Share on other sites More sharing options...
rainey06au Posted October 21, 2018 Share Posted October 21, 2018 Here's mine behind R2339 Mallard. My Dyna also derails in a couple of areas of my layout in the same fashion as mentioned before... leading wheels, they actually ride out of the rails on shallow bends, not tight ones.. I've watched it hop on a turnout, and a sweeper. There also appears to be a strange print blemish above the 'bay window' on the measurement wheel side which is bugging me.

Silver Sidelines Posted October 21, 2018 Share Posted October 21, 2018 (edited) Then there is the Bachmann version.1938 revisted ? No problems with the running. Just a reminder there are two videos here, one in the light and one in the shade.: https://youtu.be/kdsm52WF-Dg https://youtu.be/FvnsaBMugoA It does occur to me that if your track work is not level or the curves very sharp then it might be that the carriage is being lifted up by the measuring wheel under the centre of the coach? Something to check? Ray Edited October 21, 2018 by Silver Sidelines 3 Link to post Share on other sites More sharing options...
