Welcome to the Illinois Tech
Model Railroaders HO scale miniature railway
system general information and history page.
Founded in 1948, our club is
located in the original Armour Institute
Building, just east of the former Rock Island Railroad. To the north of
this building on the campus of one of the nation's foremost technical

view of the club to the east and west are rapid transit lines of both
and traditional design.
Our railway system is being
developed to represent a fictitious railway
operating between the cities of Chicago and Peoria. We are attempting
capture the flavor of a medium-size railroad with characteristics
to those found in Illinois. The club railway line is the Camp Armour
Boulder Junction (CA&BJ), or "Cabbage" as we affectionately
In addition to our mainline
railroad between Chicago and Peoria we
operate a shortline with connections at Streator, Wilcox, Rockdale, and

turnouts (switches) thus routing trains, controls our Chicago passenger
terminal. Hand laid track and hand built turnouts are another feature.
Our railroad is also cab control operated with the ability of
