Tender drawbars and platforms

I was wondering if anyone would be so kind as to photograph the drawbar arrangement for their tender locomotives and post the picture here. I have a "Billy" locomotive, which I built with the optional tender available from Roundhouse. I had to fashion my own drawbar, which works but I feel it looks rather toy-like; I think it would look better with some kind of decoration like some dummy hoses or something. Also, I would like to build some kind of footplate between the locomotive cab and the coal door on the front of the tender. It would have to swivel in some way and I'm not sure how to do it.
In short, the tender does not look like it is attached to the back of the locomotive in the same way as a real one would be. This is what I get, I suppose, for grafting a tender onto a tank engine.

I currently cant get any pictures of how my grandad has made his drawbars and my description would probably be confusing. However the fall plate does not have to be made to swivel left to right. He has fitted one to a billy and it works fine without. Basically he has used hinges from old glasses and fitted the place to the locomotive (instead of tender) the plate can then go up and down of course as the track requires. To allow it to go round sharp curves it isn't straight edged, but has a part cut out so that on a sharp radius it doesn't hit the tender sides and cause a derailment

That's actually very useful information. I hadn't thought of the need for the "fall plate" (learned a new word!) to be able to move up and down but of course you're right. THanks!

On the Ffestiniog Blanche has a fall plate, but Linda did (does?) not. Also missing fall plates are Prince and Palmerston, with just a centre buffer separating loco and tender.

If I go to my grandads over the holidays I will make sure I photograph his method for you. I think on one loco the tender has a swivelling flat bar where the hook would usually go, with a large rounded dumb buffer. The loco end just has the normal buffer and the flat bar has a slot that hooks onto the normal hook. It's much easier if i take pics though rather than try to explain. AS tony has said above you don't have to have a fall plate, but personally in the world of small scale stuff the gap between loco and tender is much larger than it should be, meaning quite a leap for the fireman! It also adds a little something and is relatively easy to do.

That's what I think, too. I've got a flat bar attached to the spot the centre buffer would screw onto the buffer beam on the engine. I used a spare connecting rod bolt so it could swivel and a little spring to keep it level. It comes out of the buffer beam too low for the pin on the tender, so I had to bend a bit of an upward curve to it so the tender end would be the right level. I drilled two holes in it, so the tender sits very close to the locomotive but can be moved a quarter inch back or so if the track has tight curves. It won't go around the very tight LGB curves at all (don't know the radius) but I can't see myself using those anyway.
I just think it looks a little mickey-mouse the way it is. A fall plate will look nicer, I'm sure.

For a fallplate, DLR Dan made a two-sectioned plate with hinges on which essentially covers the gap. It screwed onto the floor of the tender and is hinged to to lift up to allow access to the connections.

The only draw-bar and fall-plate I have piccies of are of Sir Nigel Gresley (60007). Not sure if that'd help. One doesnt realise quite how big she is until you are underneath helping a mate fit OTRM equipment etc.

I've got this if its any use Keith

Thanks, Dan. That's more or less what I have already, except the Roundhouse tender doesn't have the overhang that yours does, so I'm going to rig up a fall plate of some kind to cover the drawbar. I'm not really that bothered by it; it's just an area where I think the engine could look better.

Sorry about the OT, but how the folk is OTMR going to work on a steam loco

I was wondering that as well?

I was wondering too, and looked it up using the "google". Turns out most steam locomotives able to run on the main line in the UK already have OTMR fitted. I didn't bother to try and look up exactly
how, but I imagine it's a pain in the posterior. Even some little 0-6-0 tanks have it. I wonder where they hide all the unsightly wires. Rather like making an entire locomotive wear one of those wretched orange vests.
I still wouldn't mind some pictures of peoples' drawbars. Shane I know you have a Fowler. I'm only mentioning it.

Unless you've got it mixed up with AWS then that's fair enough, they've had them for years and only need simple wiring and magnets etc but how the hell does OTMR work on steam loco's, you can't exactly wire it up to the regulator etc to monitor how much power your applying etc

Bl00dy 'ell, they can even spy on you while driving steamy's now!

Some have both AWS and OTMRand yes they are a pain in the posterior toinstallA mate of mine runs his own company installing it on classic diesel traction and on steam.

I can understand for AWS and TPWS, but there isn't much point in OTMR in steamy's
Next thing you know they'll that GSMR installed as well

OTOH if OTMR is a precursor for ERTMS use.....

Well, to run on the Mainline they have to conform to Mainline standards . No if buts or maybes
