Newby with a Question, All of my Live Steam Locos are G Scale..

[Rob1962]

I have an Accucraft Livesteam Forney G scale
120:3 And a few others such as Accucraft Ruby and a few others,I purchased a G Guage caboos for the above Locos it and it fits on the track, but it is alot Larger than my locos where did I go wrong? When I purchased it all it said was G scale I did not realize there were different size G scale what should I ask for for the above locos? Next time I’m ordering a loco and a side from Accucraft what other freight cars or passenger cars also sell what I’m looking for the Accucraft cars are Big Bucks a tender is $450.00 Below in the background is the Large Caboos in the Background.
Any info on the above would be greatly appreciated by me thank you.

I have an Accucraft five steam Farley G scale
120:3 And a few others suck as Accucraft Ruby and a few otheres I purchased a G Guage caboos for the above Locos it and it fits on the track, but it is huge bigger than my locos where did I go wrong? When I purchased it all it said was G scale I did not realize there were different size G scale what should I ask for for the above logos? Next time I’m ordering a logo and aside from Accucraft what other freight cars or passenger cars also sell what I’m looking for the Accucraft cars are Big Bucks a tender is $450.00 Below in the background is the Large Caboos.

Hello and welcome to the forum Bob.
I believe that the Ruby and the Fairlie locomotives are representive of smaller locomotives used on some narrow gauge railways. The bobber caboose is designed for a 3 foot gauge track whereas the locomotives are designed for smaller gauges.

Hi Rob, and welcome to the Forum. As casey jones snr has said, there are many different prototypes, ranging in size from almost miniature railway size right up to massive articulated locos.
What makes it harder is that many of the manufacturers have a 'rubber ruler' approach and adapt designs to work for them; models may look like they portray a specific loco or piece of rolling stock, but don't. And then, as you've said, you are modelling in 1:20.3 (as am I: welcome to the club!), whereas many models are 1:19. We are working at 15mm/ft, while they are 16mm/ft, which makes quite a difference!

Ultimately all you can do is learn who builds models that work in the scale you are using. Taking a loco or a wagon with you (or memorising their dimensions) when purchasing a new item can help -but this is not possible when buying online, of course...

And finally, as much-discussed on here, G Scale is not a specific thing/ratio etc: it is an umbrella term for the larger (garden) scales, and includes (but is not limited to) trains running on 32mm and 45mm gauge track. Yes, it's confusing!

Are all these people G-Scale? According to E-Bay they are. Tbh the guy sitting looks like he's from Mars.
