Legacy Train Control System Stabilization

A migration to emulation systems using Osprey/DX coprocessors was carried out for a total of 19 PDP-11/84 systems. In this case constructive solutions for the aspired objectives of simple and rapid replacement of complete systems for service purposes were found. With just a few adaptations to the system software, it was possible to significantly increase the system performance and therefore the system reliability. Additional programs extract system variables from the running original software and then process them online for display on a system status monitor.

EQUIcon guarantees support for all systems since the time of installation.

Timeframe: 2005 to present day
