Continuity Bonds / Rail Signal Bonds and TLJB Bonds

What is Continuity Bonds / Rail Signal Bonds and TLJB Bonds

1. Continuity Bond - this is a wire connected to 2 consecutive tracks to maintain electrical continuity. The welding is done on the rail head (top of the rail track, below 1/2 round on which the wheels roll). A set of two moulds are used to achieve the joints (LH - Left Hand & RH - Right Hand). The wire size and length are fixed as mentioned in the enquiry. The wire is Copper and its capped at both ends (by a hammer head die).
Normal Cable Size  - 10sqmm – 4.05 mm dia

2. TLJB - this is a connection from rail web (centre of rail track)/ earth pipe to TLJB (equipment) terminal. Here again LH & RH moulds are used. The wire sizes can be different. It is also known asTrack Lead Joint Bond / Track Lead Junction Box

Normal Cable Size is- 35sqmm – 8mm Dia

Both tasks are simple to perform provided you can source the continuity bond wires
(1). Weld metal required will be 25g for 3/16 dia cable size.
A kit comes with the following items:
• 100 Bonds
• 200 Shots
• 2 replacement Molds (Right & Left)
. Flint ignitior
A Hammer Die

Bonds can be made in the field using supplied copper alloy signal cable, or your own cable, a copper sleeve, and a hammer die. 

TLJB MOULDS: used to make jumper, switch, bootleg or signal bonds to the web of the rail.
