Serco Sleeper Charts

[Paul Duck]

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!

It's on the second page of the booking process when you book tickets through the website. This is what it looks like:

The Serco Sleeper hotline does seem to be "busy" for a surprisingly large proportion of the time. Though come to think of it, it might have been me who was on the line at the time causing you to be put on hold! Sorry about that if so.
