Guard Rail Sleepers

ControlIt Guard Rail Printed Circuit Board Sleepers. The top pair of sleepers (one V board, one straight board) are for double track locations where trains travel on the line in one direction. The bottom pair (two V boards) are for single tracks where trains travel on the line in both directions. Click on the image to enlarge.

ControlIt Guard Rail Sleepers are used to neatly and securely hold inner guard rails or check rails in place.

Guard rails are generally found where there is confined clearance, such as bridges, tunnels and level crossings. Check rails are found on sharp curves adjacent to the inner rail, the outer rail, or both rails. Guard rails and check rails are used to keep the wheels of rolling stock in alignment to prevent derailment.

ControlIt Guard Rail Sleepers are custom printed circuit boards (PCBs) scaled from official New South Wales Railways (NSWR) drawings and the Data Sheets Trackwork Manual for the New South Wales Railways (Note: product dimensions may vary very slightly due to manufacturing tolerances).

The Guard Rail Sleeper boards are designed for many applications:

Single track guard rails: trains travel the line in both directions, guard rails are formed to a V at both ends
Double track guard rails: trains travel in one direction on the line, guard rails are formed to a V at the leading end and are straight at the trailing end
Check rails on sharp radius curves as per the prototype
Flangeway clearances at road crossings, for track embedded in paving, bitumen, asphalt or concrete, or for tram and light rail lines

Individual solder points for the rails represent sleeper plates as used on the prototype. The top finish applied to the boards restricts solder to the sleeper plate areas, thereby electrically isolating the inner rails from the running rails, and resulting in a neat and durable track join.

Guard Rail Sleepers are suitable for a range of HO scale track. For modelling trackwork to NSWR prototype standard, the spacing between the track rail head and the guard rail head is 2.34mm, which may require the removal of any plastic sleepers between the guard rail sleeper boards.

For guard rails on curved track, the sleepers can be cut and soldered to the rail separately to suit the radius. The sleepers have been numbered to assist in installing them in the correct order. A cutoff disk in a motor tool can be used to cut the webbing between sleepers.

For installation of long lengths of guard rails where gluing in place may be less practical, straight board sleepers can be added in intervals between the end boards.

To use the Guard Rail Sleepers:

Remove the plastic sleepers from your track and insert the guard rail sleepers in their place under the rails
Solder the rails to the PCB solder points
Form the guard rails and solder in place, starting any rail bends on sleeper number 7 (Hint: filing a small V in the guard rail web at the bend point with a jeweller's file can help with making the bend)
The guard rail sleepers and guard rails can be held in place with glue (for example a 2-part epoxy for a strong join)
The sleepers can be painted after installation

The sleeper plate areas on the PCB sleepers may also be used to connect wires for track power.
