| 20120261524 | ADJUSTABLE GUARD RAIL SYSTEM FOR RAILROAD TURNOUTS - A structure and counter system for railroad switching, characterized by a base support plate with a lower flat surface which on its upper side includes a first flat section with two protruding hooking elements that hold the skid's inside tab on the rail where the wheels roll on, and also includes an outer section of greater thickness that defines a stopping device that ends on the border of the skid's outer tab within the same rail. This base plate includes a wall perpendicular to the upper surface, covering its width, with a flat internal surface adapted to receive a fixing plate that receives the outer side of a counter rail arranged over the first flat section and separated from the hooking elements; thus being parallel to this rail. | 10-18-2012 |
| 246465000 | Crossings | 2 |
| 20080245931 | RAILWAY DIAMOND CROSSING - A modular railway diamond crossing incorporates sets of acute and obtuse angle castings. The rail connections to the castings have a fine taper to minimize joint impacts. The castings are spaced apart with a combination of rails and cast blocks. The outside block is a tapered design that maintains the flangeway and holds the castings and rails together. The inside block comprises a tapered common center casting. This unit also maintains the flangeway and a longitudinal distance between the castings. The center casting is a common part to all such crossings regardless of the crossing angle. | 10-09-2008 |
| 20140034788 | ELEVATED FROG AND RAIL CROSSING TRACK ASSEMBLY - A crossing panel includes a pair of intersecting rails, a pair of crossing line rails, a plurality of railroad ties supporting the crossing line rails such that the crossing line rails are angled upwardly from a base elevation toward the respective main line rail and terminating such that a tread bearing surface of each crossing line rail at its terminal end is at a height above the crown of the intersecting line rail, an external frog casting being aligned with and secured to the terminal ends of the crossing line rails and having an external frog tread bearing surface substantially above the crown of an intersecting line rail, and transitional guide castings disposed between the intersecting rails and respectively aligned with the crossing line rails. The transitional guide castings are substantially horizontal, and each has a crown maintained at a height sufficient to maintain a railcar wheel of a train wheel set above the intersecting line rails. | 02-06-2014 |

| 20110011986 | SWITCH WITH MOVABLE FROG POINT - In a switch including a switch frog ( | 01-20-2011 |
| 20110042527 | SWING NOSE CROSSING - A swing nose crossing has the swing nose ( | 02-24-2011 |
| 20130032675 | LOCKING DEVICE FOR CROSSINGS WITH MOVABLE FROG POINT - Locking device for crossings with movable frog point, including a cradle support with a central recess into which a movable frog point with transverse displacement in order to place thereof in two steady end positions is housed; characterized in that it comprises a pair of side left ( | 02-07-2013 |
