TI21s are used all over the place in AC and DC electrified areas. They are prolific at Ashford (AC and DC), Dagenham Dock and Ebbsfleet (less sure about the last).
TI21s have an ASSC under 12kA fault current care of RLE (read CTRL which is now HS1 of course). However, I think some reading is required of earthing practices of AT and BT based electrification systems and some understanding of the EN standards.
