I received a couple of MDS-Modell Haik wagons yesterday. They're supplied with Rapido style couplers, which I've eliminated from the rest of my stuff, so the first job was to fit something else. The bogies have the same coupler mount as Kato's RhB coaches, so it's easy to fit a Kato close coupler arm.


This looks much better than before, and still copes with 150 mm radius curves and S bends.




Coupling to a Kato coach is not so easy - there's a significant height difference.


Once coupled, the coach is lifting the front of the MDS bogie.


I've got another selection of Micro Trains couplers en route from Yankee Dabbler - hopefully I'll be able to get something to work and be the same height as the MTL couplers on my locos and end coaches. Or I could reduce the height of all my MTL couplers and call it a new standard.

Hullo Jim,

I've heard some folk have reduced the height of the HAIK wagons by shaving off a 1/2 mm of the boss that the bogie fits to.

I've yet to check my own HAIK. I'm not yet a gentleman of leisure, and still working full time as key personnel....

Yes, that's something to look into later on. It will reduce the clearance between bogie and body, so I need to sort out the couplers first. The Haik looks tall against the EW1, but the difference is much less against a GEX coach.

After some experimenting I've got a workable solution for fitting knuckle couplers to the MDS Haik wagons. First I cut away all of the MDS coupler mount.


Then I attach a plasticard mount using epoxy adhesive.


Finally I attach a Micro-Trains 2001 coupler using epoxy adhesive.


I did experiment with using screws to attach the coupler to the mount and the mount to the bogie, but this reduces the clearance between bogie and wagon underside. Epoxy adhesive's slow setting time (compared to superglue) allows everything to be correctly positioned before it sets.

The coupler protrudes a bit more than I'd like.


The coupler knuckle centre line is 4 mm above the track (Dapol standard) rather than the 5.5 mm used by Micro-Trains. It's still a bit close to the brake hoses, even though I've filed down the top of the trip pin.

The other end uses a shorter coupling as the bogie is nearer the end of the wagon. Fortunately the Micro-Trains 2001 pack includes short and medium length couplers.


There is now quite a bit of clearance between the bogie and wagon, so I might file down the bogie mounting boss to lower the wagon. Then I might need to cut away part of the brake hoses to stop them catching on the coupler on tight curves.

Unfortunately epoxy adhesive doesn't work well on these plastics. (A problem I've also found with the coupler modifications I described here: https://www.ngaugeforum.co.uk/SMFN/index.php?topic=50223) It's OK for general use, but any rough handling, such as when filing down the plasticard bracket, tends to pull them apart.

Some types of plastic are notoriously difficult to glue, due to their slippery surface. As an LGB man, I have found this quite a bit!

I've often used a soldering iron to melt things together, or solvent weld as used by plumbers....

Ah, the solvent weld is a good plan. I think my tin of it has probably dried out by now - it's 20 years since I last needed it. I've seen silicone caulk suggested elsewhere, which I also have a dried out tube of.

Time to experiment on some sprues and offcuts.

Latest kato RhB conversion - "Excellence class":




Windows and corridor connection filled in, gold stripes added, new 3D print interior.

Waiting for a jumper set to fill that very stark rear end, not sure if getting some "excellence class" (and new Aps1321 number) decals made would be worth it - so small!

I've finally completed my pair of "Lb" flat wagons with "coop" swap body containers.

Has anyone painted their rails white for the summer season?

Interesting video Jim!

It's also done on UK railways, but this is the first time I've seen it done on the RhB.

However, I won't be doing likewise on my layout....

I recently started following the RhB on Twitter - they posted a link to that video a few days ago. My Twitter feed is being taken over by railway related stuff. There's no hope for me now.
