I posted this elsewhere and then realised....:
we went up the ArcelorMittal Orbit, must say fantastic view from the top and the family enjoyed the slide down, first time I've been in that part of london, very nice and some interesting food places at the Westfield food court....
I remember when the Westfield Centre/'lympic park/Stratford International was the site of a railway depot. Seriously, that place has changed out of all recognition, I couldn't beleive it the first time I saw it!
The last time I was ever at Stratford TMD must have been in the early '00s* when it had all but closed, and we found a shed full of locos, incuding stored/withdrawn class 58s, which to a Scottish enthusiast were pretty exotic at the time (still are in fact).
The place was deserted, so I was able to examine the '58s 'properly', which made it all the more memorable. I only wish I had taken more pictures.....
* - It says it closed in 1997, clearly as a full depot, but it was still used as a stabling point and/or for the storage of locos for several years after.
