The heating on the switch around the 13 minute mark seems to have failed, and the driver is unable to force it to properly change manually, causing this tram on line 9 to detour onto line 7 for a bit.

The tram is able to get back on its own line after turning right at 33 minutes, driving along line 1 for a couple blocks, and then turning left at the next switch, back onto its own line.
