## Abstract

A tramway track drainage device includes a drain channel section (5, 6) provided with two ends, at least one end being provided with a wall (14, 16) closing the end. The device further includes an opening (41) created in the wall (14, 16) to form an inspection window for a cable connection (80) with a rail (2) and a plug (60, 70) for closing the opening (41), removable from inside the drain channel section (5, 6).

## Claims

### Claim 2 (depends on 1)

Device according to claim 1, further comprising an orifice (81) which is distinct from the opening (41) and is created in the wall (14, 16) for the passage of a cable (80), the wall (14, 16) further comprising a bottom outlet orifice (13) for guiding a flow of liquid to the outside of the drain channel section (4, 5, 6), the orifice (81) for the passage of a cable (80) being disposed between the opening (41) to form an inspection window and the bottom outlet orifice (13).

### Claim 3 (depends on 2)

Device according to claim 2, further comprising a seal (82) establishing tightness with the cable (80).

### Claim 4 (depends on 1)

Device according to claim 1 ims, wherein the plug further forms a core (50, 70), the core (50, 70) projecting from the wall (14, 16) on the side opposite the drain channel section (4, 5, 6), the core (50, 70) being intended to occupy a space between the opening (41) of the wall (14, 16) and the connection of the cable (80) with the rail (2).

### Claim 5 (depends on 1)

Device according to claim 1 ims, wherein the wall (14, 16) comprises a first layer (42) of a flexible material and at least one second layer (43, 44) of a rigid material.

### Claim 6 (depends on 1)

Device according to claim 1, wherein each of the ends of the drain channel section (4, 5, 6) is provided with a substantially similar wall (14, 16).

### Claim 7 (depends on 1)

Device according to claim 1, wherein the plug (60) further comprises a spout (61) for the flow of liquid coming from a rail (2) towards the inside of the drain channel (4, 5, 6).

### Claim 8 (depends on 7)

Device according to claim 7, wherein the plug (60) comprises a flexible material and a deformable structure, the plug (60) comprising a locking surface which is active when the spout (61) is in a guiding state.

### Claim 9

Drainage kit for a tramway track, comprising at least one first section (5) and at least one second section (6), each of the sections (5, 6) having two ends, at least one end being provided with a wall (14, 16) closing said end, an opening (41) being created in the wall (14, 16) to form an inspection window for a connection of a cable (80) with a rail (2) and a removable plug (30, 50, 60, 70) for closing up said opening (41), the drain channel sections (4, 5, 6) each being intended to be mounted substantially perpendicularly and facing one another on either side of a rail (2) so that each opening (41) forms an inspection window for a connection of a cable (80) with the rail (2).

### Claim 10 (depends on 9)

Drainage kit according to claim 9, wherein the plug (60) comprises a spout (61) for guiding a flow of liquid coming from the rail (2) towards the inside of the first drain channel section (5), it being possible for the plug (60) to be fitted in a removable manner from inside the first drain channel section (5), the opening (41) of the first drain channel section (5) having a cross-section that is strictly larger than a tubular portion (62) of the plug (60) forming the spout (61) that is to extend towards the outside of the first drain channel section (5).

### Claim 11 (depends on 9)

Drainage kit according to claim 9, wherein the plug forms a core (50, 70) which is to occupy a space between the opening (41) of the wall (16) of the second drain channel section (6) and the connection of the cable (80) with the rail (2) so as to form an access chamber (90) to said connection from inside the second drain channel section (6).

### Claim 12 (depends on 11)

Drainage kit according to claim 11, wherein the core (50) is hollow.

### Claim 13 (depends on 12)

Drainage kit according to claim 12, wherein the core (50) comprises an additional wall (51) which is substantially parallel to the wall (16) of the second drain channel section (6) after assembly, said additional wall (51) having a cut-out (55) for the passage of a cable (80) from the inside of the second drain channel section (6) to the connection with the rail (2).

### Claim 14

Drainage system for a tramway track, formed of at least one drain channel section (4, 5, 6) having two ends, at least one end being provided with a wall (14, 16) closing said end, an opening (41) being created in the wall (14, 16) to form an inspection window for a connection of a cable (80) with a rail (2).

### Claim 15 (depends on 2)
