Hinged Derail with SideKick Derail Booster

1-way Hinged Derail (left throw) with 1-way SideKick Derail Booster (left throw).

When used with a hinged derail, a SideKick increases the likelihood of effective derailing because wheels on both rails will be guided off and into the ballast.

SideKick is installed opposite a hinged derail on the same two ties. Like a hinged derail, SideKick folds down between the rails when not needed.

In operation, the worker first throws the hinged derail onto its rail. He then steps over and flips the SideKick flange onto its rail. Each unit can be padlocked on or off the rail.

SIDEKICK Derail Booster must always be used with a derail. It cannot derail by itself. The image above shows a left-throw hinged derail with Pop-Up sign and a left-throw SideKick on the opposite rail.

How to order SideKick Derail Booster

If you are adding a derail booster to an existing derail installation, give us the part number of the derail and the direction of throw (left, right, or 2-way). If you cannot identify the size and part number of your derail, please fill out the booster sizing form and we will supply a SideKick that will fit your rail height and throw direction.

If you are ordering a new derail and booster, by filling out the derail sizing chart we will have the information we need to correctly size the booster.

As with derails, SideKick should only be installed on fully exposed wooden ties.

Derails need to be sized to fit your rails.

There are many sizes of rail found in railroad tracks. Hinged and retractable derails need to be carefully fitted to the height of your rail.

We need to know either the height of your rail abobve the tie ...

... or

the rail size and section which is stamped at intervals along the web of the rail.

rail web identification

The markings are a code which precisely identifies your rail.

Out of our four standard derail sizes, we will supply the one closest to your rail size. Installation of the derail may require notching into two ties to lower the derail or shimming the derail to bring it level with your rail. (For shimming we can supply pre-drilled steel shims at nominal cost.)

We will send you a sizing form on receipt of your order, or click to download a pdf.
