Welcome to the Forum.

I presume when you say 'Vertical' motors you mean the type nick-named as 'Pancakes'? There are more modern versions of these still made I understand. It is possible to access the service sheets from the Hornby website www.hornby.com. Spares are available from a number of people including www.scalespeed.co.uk and www.modelspares.com.

Hope this is of help,
Regards,

The X04 evolved into the X03 around 1976. It overlapped with the increasing use of 'can' motors bought in by Hornby and even Pat Hammond's detailed history of Triang Hornby cannot say what the last loco to be fitted with the X04 or its direct successors was.
