摘要：
A rail pad (1), for electrically isolating a railway rail (2), comprises a rail seat portion (11) for supporting a foot of the rail (2), a pair of upstands (12) joined to opposite edges of the rail seat portion (11) of the pad (1) by respective webs such that respective channels (13) for directing water away from the rail are defined between the rail seat portion (11) of the pad (1) and each adjacent upstand (12). Such a pad provides improved wet electrical resistance.
