It seems odd that as LUL attempts to cool down the tube, it is introducing
giant electric projectors at many stations, along with the illuminated
moving panels on the escalators. The stories in Railway Herald this week,
page 5 about cooling down, and page 6 about the heat producing equipment,
seem to show a lack of joined up thinking!

What might be more sensible is for equipment at every sub surface station to
be reviewed and every heat producing item examined to see how its heat
output could be reduced or eliminated. Every little bit might help!
