What is meant by Inside Frame or Outside Frame?
One,the frame is outside the drivers..
The other, the frame is inside the drivers.
Outside frames used mostly on narrow gauge roads because the firebox could be wider than the firebox on an inside frame loco. They were called mud diggers because the wheel weights sometimes could stir up the ballast outside the rails.

One class of NG locos , not Forney's, were affectionately named the "Mud Hens" because they would often derail on lightweight rails and then scoot across the ties like a waddling hen.
An outside frame would also allow a lower firebox which would give a lower center of gravity.
Do a search for: forney locomotive frame. You will find a lot of info.
The 0-4-4 seems to have been the most popular wheel arraignment. Many where first used on elevated passenger lines before the advent of electric railroads.
I remember reading some years ago that that they where run as 0-4-4 and eventually run as 4-4-0 if I am correct. Logging and some shorelines bought them up from elevated lines.
The state of Maine had a bunch of two foot roads running Forney's as a 4-4-0 back in the earlier 1900's. I have seen a few up in that state on a visit.

Thanx that is what I wanted to know. Again thanx.

I have included a link with info about this loco as many never take time to search out a subject. Many links you can store. Some say Wikipedia has mistakes but a large part of info in Wikipedia links can be accurate. Very easy to do cross references with the Internet today.

This information is not correct.
The 2 small Two Foot Forney's that ran as cab forward's were used on the B&B line in Mass for just 9 months some time in the late 1870's or so.
None of the Two Foot "Forney" type loco's that operated in Maine ran as cab forwards.

I was suppose to say, cab forward on elevated and normal in Maine and some other roads after the elevateds got rid of them.
