Model 236-382 Obstruction Gauge

 Obstruction Gauges are used to comply with FRA required tests of track switches. They are used to determine if a power operated switch or a hand operated switch and lock movement has been adjusted properly. Proper adjustment is deemed to occur when the switch cannot be locked up when the appropriately sized obstruction is placed between the switch point and stock rail, six inches from the end of the switch point.

The design concept S&C Distribution Company has employed provides four gap gauges of standard values and in combinations that enable fast change over to values used for different tests. The design also assures more stable, self-retaining mounting to the rail during tests.

Gauge No. 236-382B (Dwg. To the left) offers the gap gauges most common to signal testing (AREMA standard). Gauge No. 236-382A provides a 5/16th inch gap gauge that addresses special adjustment to M-23 Switch Machines where the practice of floating off the lock rods occurs. At locations where a split point derail is operated with a switch machine or a hand operated switch and lock movement, we offer a special gauge, No. 236-382C, where a ½ inch gap gauge is provided.

Model 322 Shunt and Coupler Tester
The widespread use of motion sensing and constant warning time track circuits has resulted in the proliferation of wide and narrow band shunts and IJ couplers. Many times the circuits are overlapped, resulting in ever-increasing problems of turning and frequency conflict. The troubleshooter needs to know the complete range of characteristics of the shunts and couplers with which he is dealing, when attempting to identify the source of circuit malfunctions.

This device permits the signalman to know the frequencies, tuning characteristics, attenuation and thru-put capacities of each device in the approach "network", empowering him to relatively quickly determine the source of the problem.

  1. Identify center frequencies of shunts, couplers and related transmitters
  2. Determine termination and signal thru-put capacities
  3. With data from tester, rule out shunts as sources of tail ring
  4. Adjust turnable couplers and shunts prior to installation
  5. Test for DC leakage
  6. Frequency range: 10HZ to 5120HZ
  7. For field or shop use
  8. Operates on rechargable, 12VDC, 1.2AH lead acid battery


Application
This highly portable device permits the maintainer to bridge or terminate signals into the shunts or couplers under test. It can be moved to the area of the track where the shunts or couplers are in service, maximizing effectiveness and minimizing time required to perform the tests.

"Sweep" Function automatically checks full range for tuning points. Graphic display pictorially shows frequency curve and tuning points.

Seperate inputs for Tuning, Leakage and Frequency Meter Tests reduce potential for resistance in switch contacts to adversely affect test results.

577 Cab Signal Code Analyzer
Handy tool for setting up and maintaining coded track circuits in cab signal territory. Connects directy to the track for track measurement, or for convenience, has test leads with clips to connect to track wire terminals in the bungalow or case.

Nominal internal hard shunt helps the 577 Cab Signal Code Analyzer deliver accurate information on the capacity of the track circuit to maintain proper current levels. Display provides usable information as the tests are being made. "No Code" LED indicates (on) when no code or no track circuit is present.

Input filtering is used to roll off the higher frequency signals on the track, either above 400Hz or above 200Hz depending on the filter option ordered. These filters will limit the influence of adjacent track circuits if those frequencies are sufficiently higher than the filter frequency. Rugged construction. Unit is housed in a weather resistant, gasketed 10 in by 10 in. by 5 in. (nominal) case. Heavy duty, low resistance, twist lock connectors couple track leads to the Analyzer.

  1. Rugged, Compact
  2. Easy-To-Use
  3. Provides code rate indicators (LED's) and code rate readout
  4. Displays code rate percent on and off
  5. Displays track circuit frequency
  6. Low pass filter options remove interference above a select frequency
  7. Requires track current to be 1 AMP to operate, measures current to 20 AMPS
  8. Connection Mode re direct track connection, track wire terms in case, and no load bridge
  9. Heavy-duty, 10 ft, #6 awg welding cable track leads, base or head clamps

Model 1008 & 1009 Signalman's Portable, Digital Data Recorder
  • EASILY TRANSPORTABLE

  • EXTREMELY LOW CURRENT USAGE - 80mA

  • WILL NOT OVERWRITE

  • I/O OPTO-COUPLER ISOLATED

  • EACH I/O HAS ISOLATED COMMON

  • I/O PORTS CAN BE NAMED

  • LIVE, AT-THE-MOMENT, STATUS OF ALL 8 I/O VISIBLE ON DISPLAY MENU

  • CAPABLE OF FIELD-EXPEDIENT, FAST-TRACK SET-UP
S&C Distribution Company is pleased to offer two data recorders that address the needs of railroad signalmen. Our Portable Digital Data Recorders (PDDR's) provide the means to monitor up to eight contact closures and/or floating outputs such as those provided by GCP's (r) or VHLC's (r), and time/date stamp their activity. The PDDR is in a package that is designed to be moved from location to location. Two units feature either a recording format that will not auto-erase until downloaded, insuring that intermittent problem events are not lost if it is inconvenient for the installer to return to the site within the memory consumption time, or one with switch-selectable auto-erase and no auto-erase (Protective) modes enabling the user to choose his recording format. Can be ordered with either a DB-9 or a USB comm. port.

Memory capacity is rated in events and/or days (16). A real-time clock/calendar date and time stamps each sampling. The memory element itself is four rewriteable, nonvolatile EEPROMs. To insure complete isolation of the equipment under measurement, the I/O employ opto-coupler interfaces. All 8 I/O Ports are provided with isolated commons.

While a computer is necessary to take full advantage of deign refinements of the PDDR, properly time-stamped data collection can begin within one minute of hook-up. Fast-Track set-up utilizes pushbuttons on the PDDR, eliminating the need for a computer altogether.

The PDDR can be powered by any of three alternatives; local battery, 120VAC (power supply provided with the unit) and an optional, plug-in, rechargeable battery pack. Current usage is 80 mA at 5 VDC (internally regulated).

SYSTEM REQUIREMENTS

A computer is used during setup of the PDDR and for retrieval and review of data. Setup requires that WINDOWS 95 (r) or above, and Microsoft HYPER TERMINAL (r), are running on the computer. Easy data file review can be accomplished using Microsoft WORD (r), WORD PERFECT (r) or most any other word processor. The PDDR is also supported by Vital Sim's Data Display and Analysis Tool.
