I've found this information from a bloke called Guy Vincent who's a fan of BTM, Bristol Temple Meads. "Of particular interest here is the Bristol Harbour Railways viaduct which carried the branch line at an elevated level alongside Brunel's Train Shed but diverging from it to connect with the steel bridge which carried the branch over Temple Gate... the line carried on at a raised elevation serving Redcliffe Goods yard (Redcliffe Wharf) to Pump Lane where it entered the tunnel at Redcliffe. En-route the 242 yard tunnel passed under Redcliff Church graveyard and several occupants had to be re-interred. The line emerged from this tunnel to cross the waterway serving Bathurst Basin on a bascule bridge." It makes you wonder if the tunnel diggers were a bit too close to the surface and there was a partial collapse with bones raining down from above.
