At the moment im commuting up to Moorgate every morning to work and have seen that the Northern Line trains seem to have their heaters shut onto the cold setting so it pumps out nice cool air and i must say it does make a difference. Is there any other underground trains that have had this done to them.

The 1996 Stock (Jubilee Line) . I think the 1992 Stock, the ones that operate on the Central do this too.

I don't think so. The Central Line is unbearably hot and stuffy at the moment. The Jubilee line however seems to be much cooler (like the Northern). I stand to be corrected, but I think the Jubilee and Northern have the same, or at least very similar stock.

It's always baking hot in the platforms and the trains  |

I stand to be corrected, but I think the Jubilee and Northern have the same, or at least very similar stock. No need for correction mate . You are totally right. Both the Northern Line stock (1995 stock) and Jubilee Line stock (1996 stock) were built by the same company, Alstom. They have the same body shells and lighting ect. The only difference is the sound of the traction motors. The 1996 stock is much louder. |

Just to add, both are also technologically different as they have different AC traction control systems (in basic terms it's kinda like pointing out which bus has a ZF or Voith gearbox). |

The Northern line stock currently runs at restricted power as the transformers and power supply cables in the tunnels haven't yet been upgraded. The motors are limited to about 60% of their potential which could be why they are much quieter |

Are all the Northern Line trains receiving new engines? Rode 2 trains today and they sounded different to what is was before

Both 95 and 96 stock were built by Alstom, but they emoploy different traction control systems. The 1995 stock uses Alstom's "Onix" three-phase AC drive. The 1996 stock uses three-phase induction motors fed from a single-source inverter, similar to those used on Class 465 Networker trains.
This would explain the difference in thier sound.

It's presently in this mode only between High Barnet and West Finchley (rest of the line still on 60% power in manual mode, though expected be phased in gradually over the next 18 months). The train still sound more or less the same, just nippier. youtu.be/a6g8_q-wo94I believe it's speed restricted to about 45mph, as apparently demonstrated from 01:23 minutes into the clip... where it seems to want to go faster. I am guessing the speed restriction will be unlocked in due course??? |
