My grandfather worked for the IHB he retired back in 1992 . He worked there almost 40 years and he liked working there . He was a switchman, operator and worked in control towers in Hammond .
When I worked out of Barr, there were no remote control units. They came in, just as I was leaving for CN. I was an engineer there. Started in 98, left in 04 for CN
I can remember when the CSX's Barr Yard in the 1960s/70s was under then the Baltimore And Ohio, and had a NEON SIGN IN REDDISH PINK that bore it's name! Barr was busy then as it still is today! Those GP15T's were so small in wheelbase to handle those TIGHT Industrial Trackage Served around the South Suburbs!
It's cool to see some of those cabooses still in service. I thought they all retired ever since the railroads switched to those FREDs & other technology they have nowadays that replaced them.
