Ten Carlow players shared in their huge tally as Colm Bonnar's men maintained their unbeaten League run with a stroll past 13-man London in front of a small crowd at Netwatch Cullen Park.
Carlow had the points wrapped up by half-time when they led 2-16 to 0-4. By that stage all six starting forwards had scored along, with half-back backs David English, Seán Whelan and midfielder Jack Kavanagh.
Full-forward Craig Wall led the rout, hitting goals in the 18th and 34th minutes. He top-scored with 2-3, while corner-forward Chris Nolan was not far behind with 1-4 from play.
Substitute Kevin O'Loughlin got both of London's goals. Bill Walsh and Brian Regan got straight red cards.
