I was wondering what scale is the Large scale trains? I'm thinking it is 1:24, but I would like to know for sure. All the Bachmann box's and adds I have seen don't say what the actual scale is. Then again I might have missed it some where.
Thankx for any help

Bachmann's "Big Hauler" line of trains is 1:22.5. Their "Spectrum" line of trains is 1:20.3.
Having said that, the proportions of the "Big Hauler" line may be stretched or compressed one way or the other (just a bit), so saying everything is purely to scale would not be accurate. It's generally pretty close, though.
Note: Bachmann makes a line of "1:20" 20-foot long cars in their "Big Hauler" product line. These are freelance models, and much smaller than their "Spectrum" 1:20.3 stuff.
Other manufacturers of large scale trains make trains ranging in scale from 1:32, 1:29 (standard gauge prototypes) and 1:24, 1:22.5, and 1:20.3 (narrow gauge prototypes). And some are better than others at noting the scale on the box.

Is that universally or Bachmann specifically?
To a much greater degree than in the N, HO, O, model train sizes, Large scale in general has used different proportional scales to employ the same 45mm gauge model track to represent different gauges of real world track with the most common gauges represented being:
Standard gauge - 4ft 8 1/2 inches (56 1/2 inches)
Meter gauge - 1000mm (39 and some fraction inches)
3ft gauge
2 ft gauge
There are others, those appear the most common.
With 1/24 scale like I'm generally settling on the 45mm gauge model track comes out proportionally somewhere around 42inch gauge such as used for South Africa's "standard gauge"; same for a couple places in Australia and Far East; and a couple trolley and interurban line here in US such as Denver and Intermountain.
And our stuff will represent both 3 ft gauge and "shrinked" standard gauge.
And some freelanced which is just itself without much concern for what it would be in the prototype universe.
Some "mix and match" is variably employed to a given individual's personal preference.
In a generalized sense, scale is looser with Large Scale than the "indoor scales"

The 1:20.3 gauge is often referred to as F-gauge.

A slight correction:
That actually should say that 1:20.3
scale is referred to
by the NMRA as F
scale.
Gauge is the distance between the rails. Bachmann and most of what are commonly referred to as large scale trains run on 45mm or ~1.75" gauge tracks.
Scale is the proportional relationship of the model to the prototype. That scale is 1:20.32 for 3' narrow gauge models such as produced by Bachmann and other manufacturers.
Happy RRing,

Jerry-
You are absolutely correct. I know the difference but used the wrong word.
I regret any inconvenience this may have caused and will not build your railroad for you due to my screw-up. This is a good thing for you as I'd probably screw that up, too.

just adding here ;)
large scale ranges anywhere from 1:32(1 gauge,G) to 1:20.3 (Fn3)

Plus the famous British scale of 16mm and the increasingly popular scale of 7/8ths....as well as Gn15, of course.

right i forgot. :-[ and i thought i was missing something ;)
I didn't see any mention of 78N2, 13.71 scale from 45mm as two foot narrow gauge.
I have built a couple dozen of these locos.

Read my post above - I wrote 7/8ths....'the increasingly popular scale of 7/8ths....'

Thankx to all the replies to my question about scale. Sorry it took me so long to reply, I have been very busy.
Thankx again
Blackie
Barry-
A couple of dozen??? You must be kidding.
