Hoping someone can help! Was completing a sleeper booking this week and the customers asked for 2 berths with interlocking doors. After hours and hours of goggle searching I still cannot find a serco sleeper berth chart any where! If anybody has a link or screenshots of all sleeper carridge layouts it would be most helpful. In the end I rang serco sleeper and after 20 minutes on hold due to high call demand (1300 on a Wednesday surely can't be that busy a time to ring), I got a very helpful lady who told me within a minute that the berth numbers I had got had connecting doors. Really shoul have asked her for some berth charts but was super busy with advance bookings. Thanks in advance people!
