1. Vp until 195k, the Marian State 3ailways Used three types of rail Switches
desig:rted 48 Is 48 II, and 48 III. 411 of these switches sstp1oyed pivot points
in which the rails were physically sepnted. Ira 195k to the present a new
type switch in which the pivot paints sacs caatimoas rails with the flamess
left off, ben been

the,old or new type switch.
Illustration 6: The exact dimenions, radii and angle or turnout for
each old type of switch are shown. Type 48 refers to the rail weight
and the Raman numeral indicates the type of switch, is, 48 in indicates
a switch using Type 48 rails with dimensions as indicated. This system
permits easy reference in designing yards and drafting blueprints.

3 since World War 12, the tingarian state Railways have completed or are planning
a number of Delta-type snitch lines which will tend to speed up tralyle by
w-.i nn varriafs railway yards and metropolitan rail complexes.
Point #1: Planned (1957) Delta-Switch line on the Ittskole-Budape , c-
Diosgyor lines to afford direct access from BudeWest to the iron plant at
Diosgyor without entering the takole yards for turnaround.
Point j2: A delta- itch line connecting the itiskole-Boureve line with the
Banreve-Osd line de.: --a was built shortly after World We 11.
Point #3: A delta-switch line at Laszentmiklos which provides access to
Czechoslovakia, through szoinak, fron Yugoslavia, without Passing through
the Budapest rail caaplex. Built in 1951.
