A press release photo of un-named prototype "DELTIC" in 1955 at Netherton Works, Liverpool.

The locomotive had arrived at Netherton for static tests following completion at Dick Kerr Works, Preston. The locomotive was first ordered by EE Traction Division at Bradford from EE Preston works on the 20th November 1951 and was coded DP1 (Diesel Prototype No.1) and was intended to be called "ENTERPRISE". Acceptance trials began in November 1955 but mainly under the cover of darkness on freight services between Liverpool and London, its first passenger working being the up "Merseyside Express" on the 13th December 1955 returning via the down "Shamrock Express" to Liverpool...
