The system does not “run on” OS/2. That is used to glue the metrocard terminals to an IBM mainframe. The subway “runs on” relay logic. Trains occupy a block because they short the two rails together, which completes the necessary circuit. Only part of the NYC subway is computerized. That part uses off-the-shelf hardware and software that I believe runs at least partly on Solaris.
- endorphone 7y agoThis seems needlessly argumentative and unwilling to allow for any editorial leeway. A subway is composed of many parts that all need to operate for the system to work. But if we want to get pedantic, the subway wouldn't exist without revenue, and that revenue is indirectly managed through an OS/2 system. Ergo, the subway runs on OS/2.
- astrange 7y agoMost subways don't pay for themselves; it's funded by the state. Really there's no reason to charge for usage except that everyone in government likes to steal money from them when nobody's looking.
