1. 1p until 1954, the Ilmgarian State Railways used. three types of rail switches
designated 48 I, 48 II, and. 48 III. All of theme Switches employed pivot points
in which the rolls were Pkisicany separated.. Irma 1954 to the present a new
type switch in which the pivot points are caatindous rails with the flanges
left off, has been used..Thi apuipAnnalizi48n VII,. 148 nix,

Illustration 3: This is a plan drawing of the new spring-rail type switch
used an all lines since 1954. There is no break in the ran at the pivot,
