Hi Dave,
As it was me you were in contact with regarding this, I just want to clarify a few things here.
Firstly, it should be pointed out that the reason you contacted us was not warranty-related.
Regarding bodies, chassis and bogies, any fundamental issues involving these parts would have been detected within a short space of time after the locos first arrived, and if there were any issues the affected loco(s) would have been set aside and replaced with an equivalent from a reserve we had put in place (in the end this was not required and the reserve stock was released).
I did also point out that we have supplies of most other parts available to cater for any warranty cases that arise. We don't offer these parts for sale at present as we have to ensure availability for warranty work for at least 12 months after the very last new A Class model is sold to the end user. One reseller was advertising availability as recently as January, so I'm sure you can appreciate why we need to conserve stocks for so long. However, from posts I've seen elsewhere, I believe the rebuilding of your loco is now substantially complete, so if you want to email me a list of the small parts still required, I'll ask our technician to check these stocks and we'll see if we can make some available for you.
