PROBLEM: Weather, time and equipment availability can interfere with proper connection or reconnection of track wires, bonds, hardwire shunts, etc. Other times, maintenance operations such as replacement of insulated joint plugs and repair of broken rail require quick, semi-permanent electrical connections. Through all of these variables, railroad operations must be kept as free-flowing as possible.

340-124 Temporary Track Wire Connector (4-Wire)
Intended to expedite the reconnection of damaged track wires, or track wires disconnected during T&S work, in inclement weather or where the urgency to reestablish train operations does not permit normal trackwire installation, the S&C Distribution Company, 340-124 Temporary Track Wire Connectors have been designed to be easy to install. Field tests in an extremely rigorous environment suggest that, if properly installed, they will maintain a zero ohm connection to the rail for a considerable length of time. Proper installation is important. Descriptive instructions are furnished with each unit shipped.
Note that the 340-124 Temporary Track Wire Connectors can be used with 70 to 140 pound rail and that the wire receptacles for the Track Wire Connector Clamp have been designed to accommodate up to four wires, in sizes from No. 9 to No. 6 AWG.
One signal maintainer with whom we are acquainted recommends that pigtails be pre-mounted to the Clamp. When it comes time to use the Connector, installation will only require crimping track wires to these pigtails. Interconnect wires are also available to use these clamps to build temporary web bonds, hard wire shunts and track jumpers.
Carry Bags - Note that Carry Bags are offered below as a means to corral the various parts, pieces and tools of a Temporary Track Wire Connector Kit. Two sizes of Bags are offered; Standard, 5 inn. x 7 in. x 12 in., and Larger, 6 in. x 9 in. x 19 in. Configurations are also offered that include the appropriate tools for the two types of Connectors. The larger bag is preferable if you intend to pre-pigtail the Clamps.

340-301 Series Temporary Power Bond Rail Clamp Connector
The Model 340-301 Series Temporary Power Bond Rail Clamp Connector (TPBRC-Connector) is a rugged, field-tested and field-proven product. When properly installed it provides a zero ohm connection to the rail with the capacity to carry traction current, reliably. It will stay in place until it is removed, even in areas where track conditions are likely to vibrate less effective connection devices off the rail.
Application is simplified to insure the highest possibility that anyone using the product can use it correctly. It will mount to rail from 70 lb. to 140 lb. in size.
TOOLS - All necessary mounting adjustments can be made with the Special Wrench offered, that includes a square end that allows tightening of the square head set screws and a deep-well socket that allows tightening of all binding and jam nuts.
CARRY BAGS - Note that a Carry Bag is offered as a means to corral the various parts, pieces and tools of a Temporary Power Bond Rail Clamp Connector kit. This is a very rugged, military-style canvas bag, with heavy-duty zipper, strap handles and hard bottom to make the load more manageable. Exterior snap-closure side pockets provide a place to separate and store tools. Bag is offered appropriately sized at 6 in. x 9 in.
