Anyone know why the 95s are prone to do this? Perhaps the cooling system isn't

Maybe the smell is the heat from the resistor grids being dissipated when
using rheostatic braking? I don't know if the Northern line can accept
regenerative braking. (i.e sending the energy collected back to the supply source)

I was on the Northern Line the other day but didn't notice any peculiar
smells, you can definitely tell the 95TS performance has been upgraded
since the introduction of TBTC on the Northern Line.

The Northern Line 95TS use newer AC traction motors and IGBT control
despite being older, whilst the Jubilee Line 96TS use DC traction motors
and GTO control despite being newer - this was because the design specs.
for the JLE Extension were frozen back in the early '90s before
widespread use of AC technology.

I'm pretty sure the 95 TS is actually newer than the 96 TS. The newer
sounding number was chosen for the newer Jubilee line to sound better, but
the trains are older, with older technology.
