Thomas Telford Locomotive - Take Two

[DLRdan]

I would think Steam4fun get the door from Roundhouse, along with some other things.

Certainly possible Dan.

Comparing my oscillating Thomas Telford smoke box door with an old Millie smoke box & door in my bits box, the Roundhouse one is a sharper casting.

So could be just that the quality of castings has dropped slightly, the mould is showing its age, or Simon has made his own moulds from the Roundhouse originals. Had the impression that he did or had his own castings made.

Difficult to see any real differences in the traverser jack castings between Roundhouse & Steam4Fun.

I take back what I said previously about the Telford being on the small side. If you've read the chatter on the 16mmngm group about the new Accucraft Decauville 0-4-0 and then read up on the details, especially the dimensions, the Telford isn't too small at all to appeal to the Garden Rail community.

Now I don't know the exact dimensions of the Telford when Mamod finally launch it but the original Telford's dimensions were:

length: 11" (280mm)
width: 4.625" (120mm)
height: 5.5" (140mm)

and the dimensions of the new Accucraft Decauville are:
length: 8" (213.5mm) excluding buffers, 265mm with buffers
width: 3.5" (89.7mm)
height: 5.375" (138.3mm)

What's the working pressure of the boiler on the Telford.

[mikewakefielduk@btinterne]

40 psi

I won't be buying one if it has a plastic sight glass then.

Here's the Telford finally tamed to run around the challenging loop part of my garden line (gradients and tight curves) without any manual intervention.

I cobbled together an inertia flywheel device made from a Zecar toy from Amazon fitted with Accucraft wagon wheels. It holds the Telford back when it wants to race away downhill and gives it a shove when it wants to stall coming uphill.

I think the Telford is currently a little underpowered for tracks like mine that aren't dead level but I understand Mamod are looking at this and considering larger cylinders. Some of you may recollect the early Accucraft Ruby had exactly the same problem and was transformed when 1/2 inch cylinders were fitted in place of the original 3/8 inch. (There was at least one other Accucraft model that was also later fitted with larger cylinders - was it the Excelsior?)

As for plastic sight glasses, I've never had a problem with them.
