Orange 1970's era Illinois Central Gulf Railroad side door caboose.

Orange 1970's era Illinois Central Gulf Railroad side door caboose., a photo by Eddie from Chicago on Flickr.

I took this photograph recently, at the Oak Park Society of Model Engineers,H.O Scale Model Railroad Club.

During the 1970's, there were still many railroad junctions across America and the greater Chicagoland area that were still using interlocking towers at the crosstracks and interchanges.

My H.O Scale model of an orange 1970's era side door caboose from the former Illinois Central Gulf, helps to recreate that era on the club layout, at a location known as East Dubuque tower and junction.

The caboose is manufactured by a company known as Centrailia Car Shops.
