Intercity tilting train ICN RABDe 500 # 010 of the SBB, together with another of the same series in multiple control, is leaving the 57 kilometer long Gotthard Base Tunnel (GBT) at 200 km/h in Rynächt near Erstfeld. On Easter Monday, the return traffic from Ticino northbound is always very heavy, the trains are reinforced to maximum capacity and additional relief trains run. So this is relief train 31184 from Locarno to Zürich through the GBT, a connection that does not exist otherwise (only with an IR "TRENO GOTTARDO" over the Gotthard mountain route with much longer travel time).
