Large Scale Thomas had his first "official" run during the NMRA convention. Here are a couple of pics....

Dear All,

It looks very nicely proportioned to my eye. 

Has anyone with knowledge of the prototype put a ruler to it to determine the scale?

Then again, has anyone ever put a ruler to the model used for T.V. and film?

W. A. Guessing: 1/32 of the length, 1/29 of the wheel diameter, 1/29 of the boiler diameter, and 1/29 of the body width, body height and overall height.

It is, by definition, 1/32 of the wheel/rail gauge, since the prototype is 4' 8-1/2" and the model runs on LS (45mm gauge) track.

I suppose we could worry about the scale and proportions of rolling stock it pulls, too.

Sincerely,

Joe Satnik 

Joe,

I'd bet it will be "compatible with large scale"...which will work just fine here in SC!  ;D

hey I got it...I wonder if we could get a shot of it with a Big Hauler Box Car or Ten-Wheeler?  That'd define it!

Thanks Jack, that looks WONDERFUL!!!!!  ;D  ;D  ;D  ;D

Bigger than I had anticipated (not a bad thing!!!)

Wow, I may wind up more excited at Christmas than the kids!

Any word on control

Supply your own controls - Thomas will be analog straight out of the box.

The size of Thomas looks good next to the Big Hauler.  It should make a great addition to any locomotive fleet and make a lot of kids, of all ages, happy. ;D

I can't wait to double-head my K-27 with the new Thomas!

Does the light go on if you turn the power on?
He looks like he has his season 12 CGI face

Thanks Jack ("analog")...and Thanks Bachmann for keeping it simple!

James, I agree, it does favor the latest incarnation of the Cheeky little engine!

That Thomas is waaaaaaay too big  to be of much use to me  :(
I will have to get one anyway, but I had hoped for a smaller block than the Annie for bashes.
We'll see how Percy turns out.

Also, will the spoked wheels be available as a seperate item?

I found out that Thomas is based on a real locomotive that was in Britain. It was an E2 Extended Tank 0-6-0T, which none of them survive. I like the Large Scale Thomas, but I don't want one.

Thomas looks accurate! They captured the size of a British train perfectly. Keep in mind that British trains are standard gauge but are smaller and shorter than American trains. Great Job Bachmann!

heres a link to a photo that must have been thomas' Granpa, any body know how power was aplied to the wheels on these loco's? I see no pistons

Cylinders were mounted under the smoke box and linked to the middle axle which was in fact a crankshaft similar to an Automobile Engine. Valve gear ran on the same axle on concentrics. All hidden away but a real terror to grease and oil.

lots of Thomas stuff here!

Wouldn't the configuration of a British steam locomotive be similar to a Heisler?

Well, as I understand it, the cylinders on a Heisler are at right angles to the loco and in opposition to each other.

On an inside cylindered British loco, the cylinder(s) are in line with the loco ie point front to rear, parallel with the boiler, and if there are more than one, are side by side, between the loco frames.

Also on British steam locos the inside valve gear is usually of the Stephenson type, although Joy valve gear has also been used esp on the former London & NW Rly. Sir Nigel Gresley used conjugated valve gear on his V2 class 3 cylinder locos and the sole 3-cylinder 8P Class Pacific 'Duke of Gloucester' uses British Caprotti valve gear.

So plenty of variations here!

btw - there is a 'real' Thomas still extant on the Nene Valley Railway, near Peterborough, Cambridgeshire, UK. It was named by the Rev W Awdry (who I met on a couple of occasions). It is an 0-6-0 but with outside cylinders unlike the Thomas in the books and was manufactured by the Hudswell Clarke loco company in 1947.

There's a picture of the Revd naming Thomas on the nene Valley Railway's website( http://www.nvr.org.uk/thomas/ (http://www.nvr.org.uk/thomas/)):

You can see the outside cylinders in this picture (below), also the cutouts under the side tanks to access various bits under the boiler, but otherwise pretty near to the 'real thing'!
