Are there currently any timetabled loco-hauled Zurich-Milan EC services? A quick look at the SBB timetable highlights two services that are booked to take 4:11 vs. the usual 3:41 shown for most services. These are EC114 (dep. Milan 09:10) and presumably the return service EC113 (dep. Zurich 17:09). Is the extra 30mins to allow for a loco change in Chiasso?
Yes these are booked Re4/4 II from Chiasso to Zurich along with EC153 07:47 Luzern-Milano and EC158 return (14:10 off Milano Centrale).
