These pictures are from a Live Steam Engine Club in Holliston, MA.
Evidently these people come from all over the east coast and Canada to these meets.

Terminology:

The scale part refers to x inches being the same as 1 foot in real life.

Club features:

There are 3 sizes of tracks; 3/4 inch scale, 1 inch scale, and 1.5 inch scale.
There are two tracks;
The 3/4 inch and 1 inch tracks coexist on the raised track.
The 1.5 inch track is on the ground.

There is a circular hydraulic train loading area where the trains are rolled
from the back of people's cars onto a hydraulic lifted track which is then
lowered and turned to move the trains onto the appropriate
maintennance/cleaning and assembly tracks.

There is another rotating hydraulic lift which connects the circular cleaning
and assembly hub stations.

There is a water and coal loading tower.

People like to give rides!.

Interesting facts:

A locomotive can typically pull upto twice it's weight.

A typical weight for the 1 inchers is 300 pounds.

There is a steam 1.5 incher that weighs 1500 pounds. It is 8 feet long.

The one inchers cost around 15,000 assembled.
The 1.5 steam one inchers can cost 35,000 assembled (8 foot one is 65,000).
I suspect the cost to make it yourself is substantially lower.

A one incher can run for about 4 hours before it needs to be cleaned (pipes, oil, etc).
Evidently real engines suffered from the same problem but it took
them a lot longer to get into this condition.

A lot of peope on the 1.5 inch track put together these lawmower or battery
powered type boxes and ride around on them. Really funny :)
The raised 1 and 3/4 inch track is mainly for the more serious people.
