I can't comment on today, but I've been out for it twice in recent times and both times it has produced. Actually make that three times, I went out once to get a sneak peek at the local to see what MK4s look like in my area too.
If you do go for it, have a great journey. It has to be said it's a fun experience on the MK4s, a bit weird when you expect to hear the underfloor engine noise (I'm clearly too used to DMUs up here!) and glide out of the station in silence!
I also like the great big vinyls on the DVTs, it makes for something different. Somehow I found the Lifeboats one to be appropriate, on a service running along the coast at least. Can't immediately recall what the other one I've seen was, but it's still eye-catching.
