1. An ultrasonic probe for non-destructive testing of a rail, said probe comprising
a housing;
an insert comprising an ultrasonic transducer and a shoe having a face for contacting a rail;
a compressed spring for exerting a downward force on said insert, assembled on top of an external side of said insert; and
a flange with an aperture provided as a cap over a slot in said insert for said ultrasonic transducer, assembled between said insert and a sled of the rail;
wherein the flange is bolted down by said spring, thereby preventing the shoe from extending more than a preset fixed amount through the aperture.
