Abstract
1472328 Railway crossing frog SOC DES ACIERIES DE PARIS ET D'OUTREAU 25 June 1974 [26 June 1973] 28055/74 Heading E1G In a rail crossing frog, having frog running rails 5 of tubular cross section capable of being connected to Vignole rails 4 by inserts 8 welded between them, the ends of the rails 5 are disposed above an end portion of a sole plate 2 of the frog which is formed with an aperture 6 to enable fitting and welding of the inserts 8. Ribs 10 locate the Vignole rails 4 which are clamped to the base plate and to a sleeper under the joint area by clips or fish plates 3. The 4 to 5cm long inserts 8, which are welded to the frog and hardened before the frog is joined to the track, have a tubular cross-section at one end and a Vignole cross-section at the other end.
