[GreenKeys] OT: Teletypes, Telephone & Railroads

[Michael O'Day]

Back in the 80's I serviced part of the Chessie System network. They sent consist info from Baltimore via dedicated phone lines at 12-1800 baud (Burroughs OEM modems) to the three yards in Chicago. They would punch one 80-column card for each train on our equipment, and sort them on an IBM model 36. Cards were relayed to the switch tower on the 'hump" in Barr Yard (Riverdale). Consist info was sent to Baltimore via the same setup from the intermodal yard (75th & Western Ave.) and from their other yard at 71st and Pulaski.  Nary a teletype unit in sight, or I might have had one sooner.

Yes and yes.  I believe the consist info would include the
train crew members too.
