That's a cracking photo, but...

I don't think that's got a wide footplate at the front of the tender. Look at the shadow around the steps, if the footplate were wider, it would have an uneven shadow line as it approached the front of the tender.

I also reckon that Richard has probably got the height of the footplate correct; on the L12s (and maybe S11s) there are raised sections of footplate on the loco, but I think most of it is at the same height as the T9.

The stanchions look to be wide, and the cladding plates should be there for sure.

I think it is more to do with the width of the platform or 'box' the crew stand on rather than the width of the footplate where the stanchion and sandboxes locate. That would be applicable to a T14 for example. A wide bodied T9 would use a similar arrangement to the L12 compared to the narrow bodied T9

Tom,

Agreed, the wooden part of the footplate is wide, which would normally be matched with a wider footplate that the stanchions bolt through. I was only picking up on the width of the metal bit. The 'wings' would have been visible from their shadow cast.

Continuing my mad dash to get the tender on its wheels for Reading.....

First the tender footplate and drag/buffer beams.

I have cut the buffer stocks off inside the rear buffer beam, as they would have been very visible, and reduced the length of the buffer ram for the same reason.

At the front end I have added strengthening angle in the corners (as I did at the rear end) and added a strengthening strip behind the front step plate. It makes it much less vulnerable at the half-etch step locations to clumsy pick up. This unit screws in to the tender top.

The chassis is a separate screw-on unit. There is a lot of detail to go on, but that will wait until after the show.

Now for the bogies.

Bit of a late night, but I have the tender on its wheels.

The basic bogies are simple affairs.

The springs and bearings repay careful cleaning up and straightening, though they are prone to break where the rod from the bearing goes into the spring. No matter, it's easier to clean up and can be readily soldered on in two parts.

This is the rear bogie which has the guard iron. To get the ride height to match the loco, I had to add bearing pads to the top of the bogie stretcher.

That's as far as I'm going for now. The tender is short on detail, but it passes muster for display purposes.

I'll now clean the loco - it's had a lot of handling over the last few shows, and then unite loco and tender for the first time.

Hi,

Back on the L12, I want to get it running tomorrow.

I have prepared all the radio control gubbins. It all fits in the tender on screw in brackets. There are 8 AAA batteries which should give 3 plus hours running time. Not being particularly experienced with R/C, I just carefully followed the wiring instructions....and was mightily relieved when it worked!.

That's compact enough to fit in most tenders pretty easily I reckon.

This is yet another constructional article I have only just come across and it has been a joy to read through. The soldering is the tidiest I have ever seen and that is saying something seeing as there are other neat solderers on this forum. I look forward to seeing the loco painted.

Hi Richard, excellent work on the loco. Are the etches / castings for the tender the same for those that will come with the T9?

Hi,

L12 test was generally successful.


I say 'generally'.... It worked and went in the right direction. Haulage was particularly impressive. However, slow running is simply not good enough. I suspect that the receiver/controller's output is not giving me anything like the sort of control that I would have with DCC. I am using a Deltang RCT-Rx65c. Any ideas about what I can do to improve the slow speed response, or is there a better receiver/controller I can use? I have obviously got the tender brake shoes prototypically close to the wheels judging from the sparks:)

Hi Richard, excellent work on the loco. Are the etches / castings for the tender the same for those that will come with the T9?

Just to amplify Steph's reply; the white metal castings will be a little better than those I am using. We have refurbished the patterns and had new moulds made. In fact the axlebox and spring unit has had more detail added. Otherwise the same.

Richard,

Gimme a call (once the Grand Prix has finished! :D) - I've got an idea to help with the slow speed control.

This is lovely, did the kit get finished and did you ever find any good evidence on what the backhead looked like. Drawings of these and the S11 are very sparse with only a side on GA drawing and other details, but not the backhead or cab.
