Ha! I went into to KL today to catch the 11:56, and reached the station just as the NMT was pulling out of pl2. Pity as I could have snapped it if I'd been 5 minutes earlier.
Do you know if this was a scheduled visit, or did it come to assess the appalling ride between Ely and Lynn ? (Speaking of which - I see that no sooner did the ESR come off at Ely Dock jn than a new one sprouted up at the Cam bridge near Chesterton).
Cheers, FP
