Re: GWR rectangular covered water tower - dimensions?

The 1":40' Water Plans show the tank sizes, e.g. at the west end of Bodmin Road, 20' x 12' x 8' (Capacity @ 7'6", 11250 gall).

Hello Keith.
Have a look at the Wiltshire County archive in Chippenham library. A lot of GW stuff from Paddington and Swindon has ended up there.
Good hunting!

Re: Bodmin General (1955)

If, as we are told, the train with the odd coach is entering Bodmin Road from the branch... Chris, I'd suggest that it is not. I've long had a problem with that caption (in GWRJ 65). It states that the photo shows the approach to the station with the southern end of the viaduct over the River Fowey...

PenBits Sprung Bogies for Bachmann 66

Now on sale from PenBits, sprung bogie kits for the Bachmann Class 66. These have presented a real problem for 'drop in' rigid EM/P4 conversions, tending to rock about their centre axles. The long overall wheelbase has also led to the bogie frames catching on the underside of the loco over vertical ...

Re: Springing RTR 4 wheel wagons

Ah, the unit of Mike's that I mentioned is an inside bearing job - read too much into your OP! However, if you're in to outside pinpoints, his units 7.01 - 7.04 are designed for retro-fit to RTR and kit wagons.

There are also Bradwell's spring plates, written up on this forum here.

PenBits Progress: Class 40 and Peak Sprung Bogies

Not quite as much progress as I'd hoped for Scaleforum, but the test builds will be there and the Peak can even run under its own steam, so to speak. It has been putting in the miles on some big continuous runs and holds the road very nicely. The 40 is still primitive 'digital' control (i.e. pushed ...

Re: NRM Deltic Conversion to P4

Also be aware that the wheels that Bachmann fit to the Deltic Prototype are significantly under scale diameter.

Ultrascale tend to stick to the (model) manufacturers' original diameter with their 'drop in' conversions, to 'preserve the original ride height' IIRC is the reason.

Re: A sprung Class 24 or an exercise in ignorance and persistence...

Check the fit of the drive unit and wheelsets into the subframe without the springs first - just in case it's not a wheelbase mismatch.

Re: NRM Deltic Conversion to P4

For the record, more recent Bachmann production Deltics have had a six-wheel drive unit, similar to the Class 47 and the NRM Prototype Deltic. Assuming that these models have not been 'updated' to use half-axles with plastic gear muffs, the Branchlines wheels with solid axles are a suitable choice. ...

Re: A sprung Class 24 or an exercise in ignorance and persistence...

Hi John, My guess would be a mismatch between the axle locations of the drive unit and the subframe. Before you open out the bearings any more, I notice that you have not removed the clips from each end of the drive unit. Are these bearing on the end transoms of the brass subframe? - there should be...
