The third section of the works was the Shepcote Lane site, between that road and the Sheffield Canal. This was the site used by Edgar Allen Tools, makers of "Stag" brand engineers cutting tools, and the layout facilities of the railway trackwork department, which became Edgar Allen Engineering, makers of some of the most complex railway crossings in the country including the major crossing built for the east end of Newcastle Central station where the tracks of the East Coast Main Line crossed the local network after leaving the station platforms. This was constructed in sections in Sheffield and re-assembled on site. With track rationalisation this crossing was simplified using a new configuration. In connection with EA Foundry (and their Non-Destructive Testing facility to ensure quality) they were the first in Britain to develop cast manganese high speed main line turnouts.
