An information screen at Tyne and Wear Metro displayed a Java error beside the scheduled train times. The timetable remained visible and appeared to keep operating, although the dialog covered part of it. Register reader abend0c4 brought the incident to The Register’s attention.

The dialog’s design points to an old Windows installation, but neither the operating system nor the Java version was identified. Possible candidates include Windows 7 in Classic style and Windows Server 2008 R2. Microsoft’s Extended Security Updates program ended for both in 2023. POSReady 7 received such updates until October 8, 2024. Those deadlines ended Microsoft’s updates. They don’t necessarily stop the software from running.

Tyne and Wear Metro opened in August 1980. Nexus has been replacing its aging trains, yet some passenger signage remains in service. Commodore VIC-20 and Apple II were among the home computers of that era.

The Java version remains unknown. Java’s troubleshooting guidance lists video-driver problems as one possible cause of this kind of failure. Java still supports many enterprise systems, but on this occasion it moved from the background to the passenger display.
