This is a rather poor picture of an EMU on the Styal line which crosses the line between Didsbury and Heaton Mersey. It shows a 1960 built Class 304 EMU, the last of which were withdrawn in 1996. Their replacements turned out to be not a modern EMU, but Class 150's and 142 DMU's! This section of line was also the first in the UK to electrified at 25Kv AC.
