This loco started her career in late October 1988 as a test engine for the entire fleet of 90s and found herself doing a lot of test trains based out of Derby mostly on the WCML and this means she is almost 25 years old.
After testing & commissioning the 90 worked passenger services for Intercity & then Virgin Trains. In the early 2000's, the 90 transferred to the Great Eastern region in order to replace the then aging class 86s.
In 2012, this engine works passenger services between London and Norwich on MK3 carriages in TDM mode with DVTs for Greater Anglia and is leased from Portorbrook.
At Ingatestone, 90001 pauses on the up line whilst working the 09:35 Shenfield to Norwich service. Network Rail were carrying out engineering work between Shenfield and Ilford on the date in question..
In the Winter of 2009, this loco was at Crewe for a major overhaul. In those days 90s use to do test runs on 6L48 and return nth on 6X41. On the above date 90001 was pictured at Rugby on test working 6L48 south..
Sporting “One” livery, 90001 pauses at Chelmsford whilst working the 15:30 London to Norwich (1p40) service. The 90 can be seen operating in push-pull mode with a DVT at the other end of the train consist.
On a sunny spring day in 2012, a picture 90001 could be found stabled in the sidings at Colchester on standby thunderbird duties vice-class 47 - the 90 awaits deployment with a driver.
A photo with a difference - the loco awaits departure from Ingatestone with a Norwich to Shenfield express service. The 90 has a reflection of herself in the Driver Only operated (DOO) platform mirror.
Looking rather bland and lifeless of colour and a distinct lack of NXEA branding, 90001 is seen at Ipswich awaiting departure with an express service from London to Norwich in cloudy conditions.
