drsolly: Simply Paul here, on behalf of the good doctor.
Using solly's final co-ords for this I checked for it yesterday and wasn't able to locate it. I checked with a past finder too and confirmed I was in the right place. With the server with the train game due to be shut down, I decided replacing the cache wouldn't be wise and so it's with a heavy heart I send The Night Mail (Mk 2) to the big cache pile in the sky.
Thanks to everyone who played, looked-for, and/or found it. I know drsolly appreciated the logs.
SP for DS. Or as I used to log on joint projects, SPuDS.
