(@ChristopherD has been messaged, asking for the previous post to be removed. Out of sequence. I posted the above to try and repair the tear in the space-time continuum and uncross the streams and unreverse the polarity)
Time for another locomotive, just to settle things down further.
LNER J17 8217 at Barrow Hill
LNER (GER built) J17 8217, a famous Norfolk boy like ex Barrow Hill resident 70000 Britannia. The J17 was often seen on freights on the Wells to Wymondham branchline along with B12 61572 and J15 65462.
Barrow Hill Roundhouse is the last surviving railway roundhouse in the United Kingdom with an operational turntable. Built in 1870, it was threatened with demolition in 1991 when the site was closed by British Rail. It was saved by a group of dedicated volunteers who have transformed it into a unique railway museum and events venue.
(PS They do NOT pronounce ‘Wymondham’ as she is wrote. Oh, no.)
My most sincere and humble apologies!
Don’t feel too bad - you’re not the only one to have done it. (Whistles nonchalantly.)
I’m really grateful for a thread on boingboing where the way 'forward ’ in the thread is so manifestly obvious, and derailments in that flow are so easily mended!
In before the thread lock(er)! 
I refuse to join any club that would have me as a member.
Trains and boats and planes … and buses.
Let’s not forget farm equipment!
