Two white worms slithered past each other high above Wassen on the morning of 14 August 2016. 500.016 on the right was working ICN 886 from Chiasso to Zürich past an unidentified RABDe500 on ICN 873 from Zürich to Lugano.
There were more tilting EMUs on the Gotthard than either loco hauled passenger trains or freights. At times it seemed there was practically nothing else about and every time a signal turned green it would be a RABDe500 or an RABe503 that appeared shortly afterwards. After a while I got thoroughly fed up of the things.
