Wheelbase is 44mm (22mm + 22mm) & wheel diameter is about 14mm

Hmm 42mm is needed.. an extra mm either side could be acceptable. Wheel diameter is correct at least

Can anyone confirm the wheelbase and wheel diameter of the Oxford Rail/Golden Valley Hobbies YEC Janus?
From a photo estimation, it would be suitable for a Terrier A1/A1X

Thanks, Matt, that's a very useful update! I'll have to explore the new J72.

You are very welcome Ian. I too will be looking at exploring the new J72, should a reasonably priced specimen come available somewhere. I'd only need one chassis to design the different bodies. I feel that I've spread myself too thin with 3D print projects at the moment though. Look forward to what you can turn up.

Never mind the 56xx. The 94xx would sit on a J72 mech nicely. Just a slight discrepancy with the centre axle placement

Some further info on this, should someone out there be considering this:

Old J72:

• 97xx
• 56xx

New J72:

• 97xx
• 56xx
• 94xx
• 57xx and sub classes

The old split chassis has a hulk of mass over the centre wheel, which precludes any side tanks that are not full depth down to the running? plate. It could be milled back but that's a whole lot of effort..

PS If anyone is wondering about the time between posts on this subject, I have not spent an entire year contemplating it! I just happening to circle back around. As we do with these niche scales.

Has anyone tried the H0 motor kits available from ARU Model in Japan? 

 

https://www.plazajapan.com/2010010000158/

 

A couple of their wheelbases might be usable (28.5mm and 31mm, a tad either side of a scale 8ft6in) and with 10.5mm (3ft) and 11.5mm (3ft3in-ish)

 

Ok, you have shipping (and likely duty/handling/etc) on top, but they do seem extremely good value at £17-odd a pop. 

 

Through a friend, I have 1 (possibly 2) on order via Plaza Japan and will report back in due course. 

I have a few of the assembled (more expensive) smaller units here but am yet to give them a run. At least the one's I have, appear to be 9V motors. Something to keep in mind.
I'm intending to design and print a couple of R&H diesels and L&Y class 21 pug bodies for them. The pug is underway.

Never mind the 56xx. The 94xx would sit on a J72 mech nicely. Just a slight discrepancy with the centre axle placement

I don't know the dimensions of the 56xx, but if a 4mm J72 chassis has the wanted dimensions I would look at the kit by Comet Models, available from Wizard Models:

This might give you better value for money over buying a Bachmann J72 for only its chassis.

Super belated response, sorry Richard.
I had more 'complete mechanism' in mind when I wrote chassis. Also, using an old J72 or possibly a new one by way of the Bachmann Spares website to save cost

An idle thought rather than confirmed dimensions sorry. Just wanted to leave it somewhere.

I think the upcoming Rapido Class 15xx has potential for a BR Standard Class 3 2-6-2T

56xx with the J72 chassis if a trailing axle is added?

I have a feeling the universe is encouraging me to continue this UK H0 line of inquiry.

A Frateschi U5B chassis popped up locally this week. The smallest of the Frateschi diesel chassis I believe.

Here in NZ this is available locally as an unpainted NZR 'DH' class.

Bogie wheelbase = 31/31.5mm = ~8ft 10in (close enough to 8'6"?)

Bogie centers = 85mm = 24ft 3.5in

Pivot centers = 81mm = 23ft 1.75in

Width (along chassis) = 24mm

Width (at centre) = 34mm

Wheel diameter = 12mm *added 27/05/22

Save for a couple of piddly weights, the chassis is entirely plastic, so it can be cut and shut/extended as required.

This chassis could suit a few of the smaller prototypes.

Both bogies are driven from a single motor and both have electrical pick up.

I would like a Class 22 to build a WR Hydraulic fleet, but I am unsure about the lack of genuine recorded sound available for decoders..

Thanks to Alans' post I went and perused the Lincoln Loco offerings.

The German DB Class V60 is well represented across European manufacturers.

I believe this would be suitable for a BR Class 14 'Teddy Bear'.

They reviewed a couple of Frateschi locos in Continental Modeller a few years ago. These were 'H0' models of EMD metre gauge export models but the size had been increased to match US standard gauge stock although this may have applied mainly to the height and width.

Howard, you are quite right. I finally went and measured what was in stock at a local model shop. While some of the "length" dimensions could be useful, the widths of the chassis were ~30-32mm. Too wide without significant modification? Also there were no examples of Bo-Bo to measure. 

Would it be possible to reupload the table in the OP?

I've been investigating some Frateschi locos and they have a couple of promising chassis.

I just need to confirm that the models match the prototypes.
