liable to connect with already known means, not shown, such as inserting intermediate layers Rubber or similar material between the rails and the underlay pegs and placing of shoes made of rubber or similar material around that part of the washer blocks that goes into the concrete with the the support blocks are cast in the stone slabs, immersed.

The double advantage of being easy to lay with the possibility of later changes and the effective vibration dampening make such a track particularly suitable for railway lines in urban areas. Because it is extremely important to limit the nuisance caused to residents by the shock * «when a train passes by. Also, since railroad lines in urban areas are mostly underground, it is important to use a laying method that reduces the construction, work on the construction site, the under-; ~ - keeping work practically eliminated and still allows later interventions.

The first tests have shown that in the frequency band from 20 to 180 Hz compared to conventional Laying the track on a ballast bed reduces the volume by about 15-20 dB, that is -5 — LOnual is lower.

An embodiment according to the invention is explained with reference to the drawing. It shows

F i g. 1 a view of the track from above,
_ F i g. 2 shows a cross section through the track along the line II-II of FIGS. 1 and

Fig. 3 is a perspective image of a partially cut-away section of track.

Two rails 1 of the for railway rails Ub-

"■ borrowed profile (these rails are in F i g. 1 and

, -Fig.3 only indicated by their axes), are on

Washer blocks 2 attached. These support blocks 2

are arranged in two rows and two of each

'one row to the other by a crossbar 3 so

connected that they have a cross sleeper of a known type

form.

The substructure on which the track is laid consists of a concrete belt 4, which is shown in FIG. 2 drawn profile corresponds to the substructure in a single-track tunnel,
The concrete bed 4 has continuous lateral shoulders 5 and spaced stops 6, which are either cast together with the concrete bed 4, i.e. are part of the bed, or are subsequently inserted into the bed 4, on the concrete bed 4 there is an uninterrupted layer 9

ίο made of anti-vibration material applied, Stone slabs 7 arranged in two rows are located

on this layer 9 . You are pressed by a bar 8 against the associated shoulder 5,

The wedge bar 8 fills the »between the two plat-

IS th rows of space in between,

Thus, the stone slabs 7 are securely held in the lateral direction by the shoulders 5 and in the longitudinal direction by the stoppers 6 , and the rails 1 are prevented from moving.

ao, 'The washer blocks 2, whichever supports the rail 1, are cast with concrete 10, which fills the recesses in the upper surfaces of the stone slabs.

The method described above is particularly interesting because of its convenience with the Veras lay that it entails. Because the concrete bed 4 is prepared so that it is the desired number of rows of panels between its shoulders 5 (two for a single track and four for a track of double direction of travel), and because of the

visible distance only these plates need to be laid and fastened by means of the wedge strips 8 will.

The stone slabs 7 do not need to be placed exactly; this facilitates the construction of the concrete bed 4.

The exact laying of track 1 takes place at the A height of the cross sleeper «, which is made up of the two support blocks 2 and the crossbar 3 connecting them exist. These are initially simply entered in the upper, hollow part of the stone slabs 7 inserted and brought into precise position; then this hollow part is filled with the concrete 10, and through this the Track held in its exact position forever.
