If you're new to Large Scale or Garden Railroading, you may have noticed that some pieces of rolling stock (even pieces labeled for the same railroad) don't look right next to other pieces. It's not your imagination. Large Scale manufacturers are using the same 45mm track (1.775") to model "real-world" prototypes that ran on 36", one-meter, 42", and 56.6" track. But for a model of a standard gauge car that ran on 56.5" track to look right on 45mm track, it has to be modeled in a different scale than a model of narrow gauge car that ran on 36" track. As a result of these differences (and some compromises and shortcuts that have occurred) you can now buy mass-produced Large Scale equipment in the following scales: 1:20.3, 1:22.5, 1:24, 1:29, 1:30, and 1:32. And all of that equipment runs on 45mm track. Worse yet, many of those pieces are labeled "Compatible with all G scale equipment."
Considering that a 6-foot tall man in 1:32 would be less than 2/3 the size of a 6-footer in 1:20.3, it's no wonder that sometimes pieces from different scales doesn't quite look right next to each other.
When I started garden railroading, each manufacturer only made a few products I could use. So I had to "mix and match" equipment from different manufacturers to equip my railroad the way I wanted. Nowdays, several major manufacturers make a full range of equipment, so mixing and matching isn't as necessary as it once was. But you may still be tempted to use something from a line you've never used. And it would be helpful to have some idea of how it would "fit in" with your current collection.
For your convenience in determining whether equipment of various manufacturers is compatible in overall dimensions, we have compiled measurements of a few freight cars and wooden cabooses, sorted by whether the models represent Standard Gauge or Narrow Gauge prototype. (In a few cases, it's anybody's guess.)
When you are reviewing this information, please keep in mind that measurements don't tell the whole story because:

* The body length of the caboose is relatively unimportant, because they are models of different length cabooses. However, you will notice that the eight-wheeled New Bright is shorter than the 4-wheeled Bachmann.
When evaluating cabooses, remember that door heights on wooden cabooses did vary somewhat, but were seldom under 6'. The following list shows the equivalent of 6' in the major garden railroading scales:
| In this scale: | 6 feet would be: |
| 1:20.3 | 3.55" |
| 1:22.5 | 3.2" |
| 1:24 | 3" |
| 1:29 | 2.5" |
| 1:32 | 2.25" |
