Speed is awesome specially in nights.. Runs on almost on time or early from ERN to ROHA. The night speed is terrible... please don't think of standing near doors. It gets late by 10 to 15 minutes max. 12202 will get full in Reservation from UD and then the furious run starts....
12201 will become almost empty after KTYM TRVL CNGR section... G8 don't have middle berths on sides :)
