Certain class 314 units are fitted with GEC traction equipment instead of BRUSH traction equipment and the GEC fitted ones make a lovely 'clunk' at the cab ends whenever traction power is applied from a stand. The electrical buzzy sound is also quite audible on all 314 units at the cab ends particularly when in notch 4. This is possible to hear in the video however due to the deeper frequencies it is much better heard/felt with subwoofers.

This is perhaps why 207 to 216 sound a little different, particularly with the unique clunk sound as they take power from a stand. It's very pronounced on 314 213, got a few videos of the 'clank' and the hum as it leaves.

More 314s actually have GEC equipment than Brush! 314201-206 have Brush and 314207-216 have GEC traction motors. Excellent vid of a 314 in fine fettle.

The hum is heard due to electricity flowing through equipment underneath the floor.
