V2 Green Arrow
Posted: Sun Sep 04, 2005 2:54 am
I've started to sort out the pictures taken during my recent visits to the Middleton Railway and National Railway Museum (York). It is going to take a few days to get them sorted and added to the site, but here are some tasters from the NRM Workshop.
During July 2005, Green Arrow suffered a failure at speed whilst hauling the York-Scarborough steam service. I am still seeking details, but it appears that the bolts holding the centre main bearing together failed.
I've heard different accounts as to what happened next, but it looks like piston blew the middle cylinder cover off.
Here's No. 60800 Green Arrow with the centre piston and motion parts alongside. Note the bent and twisted shape of the centre main con rod, and what looks to be the remains of the centre cylinder cover.
This image has been artificially brightened to show the centre cylinder bore in the monobloc casting. This is only visible because the cover has been removed.
Here's a better detail picture of the parts that have been removed from the centre cylinder and motion.
