215-15 Dual-Purpose Walking Wheel

Field-tested by knowledgeable railroad signal personnel, our unique design provides a stay-on the-rail Walking Wheel that is self-guiding and surprisingly easy to propel down the track. During the final field trials, the evaluator was pushing the Wheel down the track with one finger. Adjustable for rail sections from 90 to 150 pounds or heavier, the Wheel stays upright on the rail without assistance under all but the windiest conditions. This Dual-Purpose Wheel is quickly convertible into one that will make fast, accurate measurements on the ground. Simply flip the Sled/Support Assembly up, latch it, and away you go. Fifteen inch diameter wheel equates to a four foot circumference, eating up the distance to be measured, and when on the ground the larger diameter allows the Wheel to measure accurately on rough terrain. Brake provided to lock Wheel when moving to second location to prevent measurement errors.

205215A Isolated Talker



The S&C Isolated Talker was developed to be a companion piece of equipment to our Slide Fence and High Water Detector equipment. Inclusion of the word "Isolated" indicates that a ground related to control inputs or the internal workings of the Talker will not ground a signal battery which may be used to power the Talker. Use of an isolated DC to DC converter is required to fully isolate any attached radio electrically, due to the antenna ground. The Talker is designed to either automatically announce the detection of some wayside hazard to train operation via radio or respond to external interrogation through the use of a DTMF code generated by a radio with a touch-tone pad. Upon receipt of the interrogation code, the Talker then generates the appropriate voice message indicating lack or presence of a hazard. A group of five pre-recorded messages (in English), appropriate to use with Slide Fences, High Water Detectors, Dragging Equipment Detectors, High-Wide Load Detectors and Hot Box Detectors can be selected by the user on set-up of the Talker, or the messages can be recorded locally with the built-in electret microphone.

506GR Shunt



Our New Guard Rail Clamp Shunt, with a Guard Rail Clamp on one end as pictured above, is a shunt that we make for applications where track circuits fall in areas, where guard rails are also used. The Clamp is designed to allow the end to which the shunt wire attaches to, fit into the flangeway. The wire connector passes over the guard rail, allowing the shunt wire to cross the track unobstructed, to another Guard Rail Clamp or conventional clamp if another guard rail is not in service. The Guard Rail Shunt is available in two configurations. One with Guard Rail Clamps on both ends, and one with a Guard Rail Clamp on one end, and a conventional clamp on the other.

506 Series, Five-Resistor Commissioning & Testing Shunt For GCP 4000 ® Island Circuits



Pictured above is the Clamp Bracket version of the 506 Series, 5-Resistor Commissioning and Testing Shunt that provides the five individually selectable resistance values (0.06 Ohm, 0.12 Ohm, 0.30 Ohm, 0.40 Ohm and 0.50 Ohm) intended for use in set-up calibration and sensitivity testing of GCP-4000 ® island circuits.

Set-up is achieved by clamping the shunt with the appropriate (generally established by the railroad engineering office) resistance value, at the receiver feed wires, then activating calibration of the island card.

Once calibration is completed, a 0.06 ohm shunt (also included in the 506 Five Resistor Shunt) is used at the attach points of both transmit and receive sets of wires of the GCP-4000 ® to satisfy the FRA requirement that the circuit will drop out on application of a 0.06 ohm shunt.

In a maintenance application, shunting sensitivity can be determined by clamping the 506 Five Resistor Shunt at the receiver feed wires and changing the resistor settings until the island circuit drops. That value is the shunting sensitivity.

Model 201A Program Transfer Device

Many S&C products employ programmable chips in their design. A method has been developed that can be used to reprogram a piece of S&C equipment without sending every device to the factory, and will not require specialized software to be installed on the computers of the users of S&C equipment. This method is our Model 201 Program Transfer Device (PTD). The design of the 201 PTD is based on a commercially available product. It will work with every piece of equipment manufactured by S&C Distribution Company that carries a chip that can be reprogrammed.

While our program-operated products do not carry the same sensitivity signal control devices and systems do, we appreciate and support the procedures railroads have developed to insure device program currency. We see the PTD being used following consultation with individual customers. They will distributed in accordance with conclusions reached with the customer. Note: due to the nature of the purchased product, it is not possible for one PTD to program another PTD.

S&C products have achieved widespread acceptance, and the condition exists that a number of different programmed devices are in service on individual railroads. A concept worth considering is that a set of PTD's be maintained for each type of product that may require programming. This practice would reduce mix-ups, and maintain a local-to-the railroad source of the current program for each type of product.

The 201A Program Transfer Device comes complete with all cables necessary for use and a 120VAC to 5VDC Power Supply, in a zippered, padded case. For traceability and determination of ownership, each PTD is identified by its own Serial Number.

DAT Series Tag-Out

Long-honored industrial tag-out safety procedures can now be accomplished with railroad signal systems. Improve the safety of signal system maintenance procedures with these blocks. Designed by knowledgeable signalmen with an understanding of both the industrial procedures, and railroad signal circuits and equipment. Blocks can address all railroad signal system devices that may require tag-out security. Available are single Blocks for various types of test nut switches and RSA terminals, networks of such Blocks for the times where more than one circuit should be interrupted and large paddle Blocks for crossing gate mechanism and switch machine contacts. Individual blocks and networks are punched and can be equipped with DO NOT OPERATE tags for added safety. Kit is available with multiple pieces of common blocks or kits can be configured by the purchaser. All blocks are manufactured from durable, highlight-red, non-conductive, ABS textured plastic. The textured surface helps to retain the Blocks in finger-type contacts.

215-2508 Series Cage Clamp Adapter

We have been asked to quote our Circuit Panels with cage clamp type fasteners to allow easy change out of the Panels. After giving it some thought, we felt that making a Cage Clamp Adapter that would mount to the standard signal (RSA/AAR) terminal was the better way to go. The user would get the best of both worlds.

We have designed two basic product configurations: a double cage clamp connector that will mount to a single RSA/AAR terminal, and one with three cage clamp connectors mounted to one RSA/AAR terminal. The purpose of the double is to allow two wires to be connected to a single terminal, the triple obviously allows three wires to be routed to a single terminal. Moving further, we have designed Adapter clusters that will mount to multiple terminal-count blocks. Even though they might fit, neither the cage clamp manufacturer nor S&C Distribution Company recommend attaching more than one wire to an individual cage clamp connector. Initially, a single connector Adapter was considered, however, it was dropped due to mechanical durability factors. Double cage clamp sets are mutually supportive resulting in substantially enhanced service life over the single connector.


We are offering assemblies corresponding to customer need. At the moment, we see in our own use the need for a Double Cage Clamp Adapter for a single RSA/AAR terminal post, and five post and six post Double Cage Clamp Adapters. Interested railroad signal personnel have suggested these same configurations and multiples of these Adapters would satisfy their needs as well. We have also added a nine-connection, Common Ground Buss (three RSA/AAR posts) for use with our 1010 Portable Data Recorder, as well as other applications. All the below include sufficient chamfered washers to put one on each side of the PC board for RSA/AAR terminal mounting.

Different configurations can be provided to address specific requirements. Please contact us at the below coordinates if your needs are other than those presently described.
