On October 11, 2023, the Bernina line of the Rhaetian Railway was characterized by very long delays, up to about 50 minutes. This was caused by a total interruption of the Engadin line between Cinuos-chel-Brail and S-chanf, which prevented the timely arrival of two "Allegra" railcars ABe 8/12 from Landquart via Vereina or caused very long delays. The situation at Alp Grüm at 13.22 h, seen from the opposite valley slope. Above, the approx. 1/2 h delayed train 4629 from St.Moritz to Tirano with an "Allegra" ABe 8/12 is approaching, it passes the 264 meter long Grüm gallery and will soon reach the station Alp Grüm, which is located on the right. In the 239 meter long Palü sopra gallery, the counter-train 4648 from Tirano to St.Moritz, also hauled by an ABe 8/12, is running on the 7.0 % gradient towards Alp Grüm for the crossing. Below is the 374 meter long Palü sotta gallery, followed by the 254 meter long Palü loop tunnel. According to the timetable, these two trains cross at Stablini, the service station between Alp Grüm and Cavaglia.
