The remover costs £35 for 50 square feet. I imagine the worker is on minimum wage of about £6 an hour.
A big Panel is about 20 square feet thats about £18, would take less than an hour to remove a panel, and
the train is already out of service as the buff is executed overnight, or during off peak hours.
£24 to remove a panel. My charge sheet quoted prices of £2500 for a panel..
