Narborough and Hinckley both used to have them, when they had operational signal boxes.
At Narborough the bell was on the end of the box, facing the station, between the up platform and the level crossing.
Hinckley's bell was on the up platform, by the door from the booking office, as the box was a little distance from the station.
Narborough: down: 3 rings, up: 2.
Hinckley: down: 2 rings, up: 1.
I understand that they were both retained until the boxes closed, 2006 IIRC, but fell out of use in the early-mid 1990s.
