test run...


https://youtu.be/JGJSa2UhoEM

they are very heavy!

westbury based 56056 not impressed! awaiting a general motors loco to take over... (the 56 has always been v slow runner though tbf)

i hope the revolution 59 is powerful

i'll switch to a class 60 tomorrow once i retrieve it from its box.

i'll add another 6 hoppers at a later date as well so it looks a bit more realistic.

I have no use for these whatsoever, totally out of region, but I've always liked them.  :hmmm:

They seem to run ok, but when you say "heavy" do you mean their weight or does there seem to be a lot of drag? I have seen two reports of poorly running / dragging wheel sets?

I am anxious to find out as much as possible as my order of 10 is imminently arriving.

I saw TomE on RMWeb saying the wheelsets rub the underside of the body (adding drag), which is disappointing.

He definitely means heavy as in weighty but possibly the drag effect too. It would be interesting to know if @bluedepot has experienced the same drag issues as myself and AN Other mentioned on the Fakebook group though. Also whether there were any broken coupling issues. As mentioned on there I am sending 3 back with broken couplings as below:



The reason for this it seems is the way they were put into the box inserts. They seem to be pushed towards 1 end and not in the preformed tray as they should be:



The end wagons also seem to suffer from the mk3 coach uncoupling syndrome where the coupling arm rises over points but doesn't drop back down meaning they will either uncouple immediately or when they next encounter a curve:



Close coupling between wagons is good though:



And finally my short video of the 7 which are ok. I have ordered 6 more too so will have a rake of 16 eventually:

hi everyone

i meant heavy in terms of weight.

there is drag as well though - and i think some wheelsets are rubbing on the underside of the wagons (you can hear the noise they make). they are not very free rolling anyway. i may try oiling the axle pin points. any other suggestions?

i didn't have any broken couplings.

the rapido couplings on the outer wagons were a tiny bit high but i didnt have any uncouplings. i don't have any gradients which helps.

i think they have made the wagons too heavy to be honest. it seems excessive.

the close couplings worked fine so far.

i do like the wagons appearance but a bit concerned with them not being free rolling - esp. for when i add more to the rake.  i dont really understand why the factory didnt try pushing them along some track to check they rolled along nicely. seems a v basic test!

cheers

The full NGN review is here: https://www.ngaugenews.com/post/review-dapol-foster-yeoman-o-k-jha-hopper-wagons

I found the wheels are rubbing on the underside of the chassis, causing drag on anything but the flattest of trackwork.

A shame as they are visually great looking wagons.

Tom.

I haven't experienced the wheel rubbing mentioned here and in the NGN review but will have a look at mine to see if this is an issue. If it is then it may be easy to dremel out a little above the wheels. I know you shouldn't have to but they are such a nice model I wouldn't have an issue with trying this. I did find a couple of axles weren't rotating as freely as I would have liked but using the age old trick of squeezing each end of the axle boxes together, like with Peco, this seemed to sort them out. I do agree that they are unnecessarily heavy though so may even take a look at 1 to see if this can be reduced at all as 16 in a rake could be tough going for some locomotives. I will also try a Hunt magnetic coupling on the end which will solve the uncoupling issue on mine as long as the magnetic is ok with all that weight behind it.

I am due to have 6 more delivered tomorrow so once I've checked for broken couplings I will have a look at what i have left and report back  :thumbsup:

One of mine suffered from the broken coupler syndrome. I agree that it is caused by the wagon not being put into the clamshell with the couplers correctly aligned to the cutout. Mine roll freely but I only have 7 at the moment hauled by a Kato Class 77, and only a test oval with a siding. Propelling into the siding over a Kato #4 turnout has been problem free. However, Before running them I did check the back to backs (one wheelset was way over at almost 8.0mm) and made sure the close coupler mechanism moved freely side to side. I have lost one of the curved handrails by the ladder.

I have a rake of 10 so far running and over half have the wheel rubbing issue, I need to think of a fix for this or it will drive me mad ! Very disappointing for an otherwise good wagon.

The wheel rubbing thing is totally unnecessary.  Anyone with a Farish BDA, pop a bogie off and have a look at the recesses underneath. Poor design from Dapol, and when I raised on their digest about the axlebox location issue on the 4mm model, the reply didn't fill me with confidence about the engineering of wagons, real or model.

I was excited for these, but now wait with baited breath. Should be here today according to Royal Mail.

Hi Gang,

4 out of the 8 I received have broken couplings, ironically both 104 and both 105 model numbers. Not even bothered to try the rolling resistance yet. A phone call to the retailer is on the cards this morning to source replacements or refunds.
I'm assuming this is going to be an expensive episode for Dapol!!

Later,

I always find things in the last place I look. weird huh??

Had my first inspection of some of these today (a fellow area group member brought some to our AGM), and because I was expecting problems, I was actually impressed.

If these things arrive in one piece they are actually decent. Having ran them all afternoon around the inner track of Kato's tightest canted curves, we had no derailments or uncoupling. Yes the inner couplings are fiddly as hell (mine will be replaced by magnetic ones), but the close coupling is impressive.

The dragging issue was apparent on some but we have developed some theories to improve this which I will report back on if any of mine suffer from it. I really hope I can put together a decent rake of unbroken coupling examples now.

hi everyone

i wonder if a shim washer would fix the problem?

the bogies pull out very easily. a shim washer might just lift the body away from the wheels enough to solve the problem.

the body is metal so unless you have the tools to mill out metal i dont know what you can do really.

4 / 8 of mine are just about acceptable when pushed along in terms of free running. they do still make some strange noises running around the layout though which suggests still not right.

the other 4 have major drag issues.

one option is to send them all back and buy yeoman pta wagons instead... but tbh i prefer jhas.

cheers
