LONDON TRANSPORT OVERVIEW
Cityfl o 650
The upgrade will deliver a new signalling system for 310km of track and 113 SSR stations, equipment installation for 191 S Stock trains, 86 Piccadilly line trains, 49 engineering trains and six heritage trains; one integrated service control centre and back-up facility; seven signalling equipment rooms; and 36 major track layout changes.
“ The chance of us putting air conditioning on the next generation of deep Tube trains is now very high. ”
Cooling off
Other challenges on the Tube include cooling the deep lines, without expending too much energy on air conditioning.
Once used for many years, the deep Underground achieves a duvet-like layer of warmth, soaking up the heat. The end result of the processes involved in air conditioning, which requires lots of power, is to add even more extra heat.
“You’ve got to fi nd another way to get rid of the heat, or of not producing so much energy from the air conditioning systems,” Waboso said.
But work is ongoing with contractors and educational institutions to solve this challenge, and Waboso said LU was “pretty encouraged by the results”.
He continued: “I think we’ve moved from it being practically impossible to now being very possible.
“If I was a betting man I would say the chance of us putting air conditioning on the next generation of deep Tube trains is now very high.
“That’s a combination of good old research and application engineering, a bit of innovation and the fact that technology has moved on. You can produce more output now with less energy.
“It has to generate some energy; it’s just trying to reduce that.”
Sustainability – the Tube’s USP
LU is also working to improve the sustainability of its trains and stations, with pioneering work at Sloane Square station leading the way on energy effi cient estate (see RTM June/July 2012).
Waboso said: “We’re very aware of our social i More stories like this at:

“The trains we are making for the new deep tube are such that we are reducing the energy profi le anyway, that means that it creates a bit of a budget for the air conditioning kits to create a bit of heat.
The work is due to be complete by 2018, with initial testing to be carried out at the Old Dalby track until mid-2013. Formal testing will start with the fi rst S Stock train fi tted with automatic train control (ATC). The test track will eventually be reconfi gured to replicate the operational environment of London Underground.
responsibilities and we have a target on not just on carbon emissions but overall emissions.
“The Tube starts from a position of being a very effi cient, sustainable form of transport, because it is mass transit.
“Each train holds over 1,000 people; that’s a lot of cars taken off the roads and it moves them far more quickly than cars could.
You
can get from one end of the Jubilee line to the other in an hour. You try driving that – it’s just a no-brainer.”
He described the ability to move lots of people very quickly as the “USP of the Tube”, and
dividing the amount of energy needed by the number of people results in a very low per- person carbon cost. Waboso concluded: “That’s why everything we do to further increase capacity on the Tube is a very good thing, not just from a customer benefi t point of view, but also from an environmental point of view.”
