To British eyes, the locomotive's bulldog nose styling was reminiscent of American locomotives, such as the EMD E-unit or ALCO PA designs[citation needed] (partly because English Electric initially planned to offer the type for export), with high noses and small, somewhat swept-back cab windows set behind them.

[8] Plans to test it in Canada fell through,[9] and the locomotive was donated in April 1963 to the Science Museum, South Kensington and placed on public display.

[8] In August 2012 it was loaned to The Ribble Steam Railway in Preston, Lancashire,[12] which is barely a mile away from where it was originally built, returning to Shildon in October 2015 [13] where it remains as of January 2023.

[15] Aside from the original issue with the severe oil leak in the phasing gear cover, significant engine components were removed for use as spare parts for the Royal Navy prior to DP1 being donated to the Science Museum[16] as the locomotive was not owned by British Railways.

[17] The Kitmaster company produced an unpowered polystyrene injection moulded model kit for OO gauge.

In late 1962, the Kitmaster brand was sold by its parent company (Rosebud Dolls) to Airfix, who did not release model kits of this locomotive.

Bachmann used laser-scanning (see 3D scanner) of the machine at the National Railway Museum Shildon to collect dimensional data of the locomotive.

[21][22] In February 2023 Hornby announced a new diecast Dublo tooling in OO gauge of the Deltic prototype locomotive, English Electric DP1 'Deltic', fitted with sound (R30297TXS).
