Exactly!

Maybe I was hallucinating

I could have sworn that I saw a post from @Ben A  saying that despite all the comments on here there have been relatively few emails to the Rev's support line about the issue.

I must confess that as a complainer I hadn't emailed Revs directly, but now I have.

I don't recall seeing anything to that effect on this particular thread and I have been following it for some days

Hi John

You are right - I have subsequently edited my post back to its original form with an explanation.

cheers

Houston we have lift off, albeit behind a pair of class 60's I have run the full 16 coach lowlander for over an hour around my layout without uncoupling. A single class 60 will pull them on the flat but over the rise on my layout I needed the pair.
This morning whilst continuing the running in to see if they freed up an more I set the lap timer going on the phone, and found that progressively the rake was freeing up, starting at 2min for a lap which equates to a constant 90mph, I found the times were coming down by approx 0.5 sec per lap, until they flatlined at about 1min 50sec. after a couple of hours of running. During this time I was running 2 sets of 8 coaches each with a single loco, changing between different class 60's, class 92's and 66's. So no loco did more than 30mins.
This afternoon I put a pair of 60's on and gradually built the full rake up, I did find a few uncouplings, but a dab of "tacky wax" soon sorted those out.
On the class 92's I did not try them on the full rake, I will have to remove the front fairing and fit the coupler to enable double heading capability on one of my units.
I did change the position of the traction tyred axels from the middle of each bogie to the rear axel of each bogie and this definitely helped with the traction.
So whilst still draggy, they do get better with a lot of running, and they look magnificent.
I have sent some videos to Revolution and if they want to post them, I would be happy for them to go up. I have tried a couple of times to post videos without success.
They do look good in the full rake, especially with the lights in the layout room turned down to emulate evening time.

@Graham The forum has never supported uploading of videos so you have to use a host such as YouTube or, in my case, Flickr

thanks, I was aware of that and thought I will have to get the grandson round to work it out.

That's mine in the post, looking forward to giving them a run.

I've been following this thread closely and thought I'd contribute where I'm at with my 16 coach highlander rake.

Visually out of the superb packaging they look wonderful, however moving them on track was initially very disappointing. As others have found some ran a little better than others but none of them great. My Revolution 92 would only move 6 coaches and even my CJM 92 only 9.

So here's what I've worked on to improve things , nothing radical just basic stuff, mostly covered in others posts. I know we shouldn't have to do this but I rather like 'fettling' things. Nothing I've done should affect warranty or any solutions Revolution may come up with.

a) Unscrew bogies and release wheelsets, remove lighting pickup etches

b) Separate the wheels and ring bearings from the  plastic retaining muffs and thoroughly clean the axle shafts and internal surface of the bearings, a high percentage of these had stuck on residue present, maybe electric conductive oil or other lubricant?

c) Reassemble the wheelsets and reset the wheel back to back measurements, make sure the ring bearings have room to move between the muff and wheel rims.

d) Check for any loose flash and paint.

e) Give them a good run - things do seem to improve.

All a bit time consuming but I think worthwhile as one Revolution 92 can now pull 12 coaches and double headed easily handles the sixteen. the CJM 92 moves all sixteen comfortably and no doubt more but It's the wrong livery!

Also I had a few issues with unwanted uncoupling with the rapidos and alternative couplings so I took the plunge and fitted 'Hunt magnetic intermediate Elite' versions, problem solved.


Ian.

I've rather given up on mine for now. I fitted the Dellner couplings but still suffer uncoupling, particularly near the front of the rake due to the weight. I am running them on an inappropriately small test loop though, so I'll cut them some slack. They're definitely improving with use. Good to hear the Hunt couplings work and that you've managed to get them working satisfactorily.

I used the intermediate Hunt couplings but they do gap the coaches a little, not sure if the close coupling will work as I don't have any.

Ian.

I've had a try with some short Hunt couplings and they seem to work, though they've only had a push around some curves and points, not a proper test so far.

Thanks very much for your very detailed explanation of your steps.
I have this afternoon gradually worked through 6 coaches and the difference is brilliant.
The one thing I think I noticed was the plastic tube the wheels plug into each side needs to have a small clearance from the bearing.
I found on the first coach even after following your steps the bogie was still very "draggy", so I made sure there was a small gap on both sides of the tube and this did the trick.
I am still making sure all the wheels and bearings are cleaned and then checked before putting back on the track.
Only the other 10 coaches to go, hopefully tomorrow afternoon if SWMBO permits.
cheers

Just had my 4 car set back from Simon at Revolution (wasn't confident going beyond swapping of wheels etc without stuffing them up)

Boy what a difference. Still not the most free running coaches I own but they're never going to be in the context of the design of the real thing. Only tested on a straight yard length of track so far, pulling and propelling but I can report...
Dapol 67- moves them easily
Sound fitted 08-moves them easily
Newer style Dapol 73-Pulls surprisingly well, propelling a struggle

I suspect the 73 will struggle with curves but I do believe that's all about the loco, possibly the worst chassis design I've seen in N

Much less frustration for me than a few weeks ago, yes I'm only having to deal with a FW portion but pretty sure the 67 would have no problem with 8,possibly more

Really impressed with Revolution's after sales service, less impressed that R Mail left them in the rain but luckily no damage done.

A decently weighted, well designed 73/9 would be most welcome Revolution. Until then I'll be pretending that DB kept the haulage contract

Would be great to hear the steps Simon performed to get them running better.

The biggest difference seems to be the 'muffs' between the wheels. They're too long, so they foul on the bogie frames/pickups. Remove them, ease the wheels out and give a few sweeps of a file.

I've got a single 92 pulling ten, and a pair doing all 16 now. Still not totally sure what to do with them long term; whether to run a short rake as was prevalent in Covid, get rid entirely or double head. I do intend to try making an Uber 92 at some point with extra traction tyres and as much weight as I can fit. Possibly relocating a speaker to and utilising the pickups in the leading coach, but that's a bit more drastic.
