From Train Mountain Encyclopedia, v 4-13 (PDF):


 * Ed Spall,  a  member  first  of  the  Los Angeles Live Steamers,  and  subsequently  of  the  Sacramento Valley Live Steamers,   developed   an   alternative method for joining track in the early 1990's.The  Spall  Rail  Joiner  is  essentially  a  scaled  up  HO track  joiner  that  is  four  inches  long  and  slips  around the foot and up the web  of the rail.  Train Mountain has done the tool and die work to produce these  joiners  in  quantity.  They  have  been  in  use  since  1992  as  a  part  of  the  Train Mountain Track System and on tracks all over the country, with excellent results.
