Well, return to Hadfield. September 1997, possibly the 19th, sees a ride out to the world's longest possession at Hadfield. 305516 does the honours on this occasion, sporting the GMPTE variation of the Regional Railways livery. The alignment beyond the bridge was once three tracks; to the left the down line, the middle the up line and to the right the up loop. The loop, with a trap point at the end, provided protection for EMUs reversing to Glossop against collisions from eastbound trains should they pass the protecting signal.
The 305s, or AM5s as they were then, were introduced from 1960 for the Lea Valley electrification. As such, the 305s were no strangers to former DC overhead structures, having spent most of their lives on the lines out of London Liverpool Street where the 1949 DC electrification programme used identical construction to the Woodhead scheme.
The Class 305s which survived into the 1990s were Class 305/2s, numbered in the 305 5xx series. These had started life as four car units and variously lost, regained and lost a trailer again as requirements dictated. The requirements of the Manchester Airport service were for four car units, and the refurbished 305s were primarily intended for these workings.
The 305s gradually displaced the Class 304s on services around Manchester as the brand-new Class 323s were delivered. The 305s would themselves be ousted by the increasing deliveries of 323s. The last workings for the 305s around Manchester were for three car units on the Hadfield services. The 323s could not go around the curve at Dinting until it was realigned to account for the extra length of each 323 car. Once that work was completed in September 1997 the 305s were again redundant with some seeing further use in Scotland on the Edinburgh – North Berwick services.
