The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
Expired or damaged railroad ties can be valuable for a variety of applications. The creosote-treated railroad ties are a valuable energy source, once they have been broken down into a manageable and consistent size. Horizontal grinders can process considerably more railroad ties than typical slow-speed
shredders. An optional cross belt magnet is recommended for this application to remove the tramp metal from the ground material, and recycling that metal adds a secondary revenue stream.
