Train service disruptions

[bikkuri bahn]

I was in Tokyo this past weekend for a short spring holiday.  Monday was my last day, intended on railfanning the inner end of the Tobu Tojo Line , but my plans were thwarted by a jumper(?) at Tsunashima Station on the Toyoko Line.  This resulted in widespread disruption during the AM hours- all through operations via the Fukutoshin Line were suspended, also affecting the Tobu Tojo Line past Wako-Shi, as well as the Yurakucho Line and the Seibu Ikebukuro Line.  I was on an express from Tokorozawa bound for Seibu Ikebukuro, the train was checked by a red signal somewhere around Nerima Station, was stopped for about 5 minutes before proceeding at reduced speed until Ikebukuro- I could see the tail end of the local train a few signal blocks ahead (signals on this stretch are three aspect), which was slowing us down. At Ikebukuro Station, I snapped a pic of the display showing the delays on the Tokyo Metro network:
