In addition, contemplated ladder assemblies for use with a commuter train, a passenger train or a railway car include: at least two rails, at least one step, wherein each step is coupled to the at least two rails, such that the rails are relatively vertical and the steps are relatively horizontal, at least one grappling footing peg, wherein the peg is operationally coupled with a rail, at least one safety handle, wherein the handle is coupled with at least one rail, and at least one commuter train, passenger train or railway car coupling fixture, wherein the coupling fixture operationally engages with the ladder assembly. | 01-15-2015 |
| 20150027341 | Portable Railcar Sill Step Extender - A portable railcar sill step extender adapted to a sill step of a railcar, the portable railcar step comprising an elongated member having two longitudinal ends and two substantially parallel surfaces, a first receptacle disposed on a first plane substantially parallel to the two substantially parallel surfaces, a second receptacle disposed on a second plane, the second plane disposed at from about 8 degrees to about 12 degrees from the two substantially parallel surfaces and a locking device. Each of the first receptacle and the second receptacle is adapted to receive the sill step and the locking device is adapted to be removably applied at one of the first receptacle and the second receptacle to prevent the elongated member from sliding off of the sill step in a longitudinal direction of the elongated member. | 01-29-2015 |
| 105444000 | Electric control | 2 |
| 20080250966 | Retractable Step - A retractable step for a rail vehicle includes a treadable region having lateral guides, a front edge, a guide region, a first roller disposed on the rail vehicle, and a second roller disposed in a guide. The guide has a configuration that is one or more of oblique, curved or bent. Also included is a transition area between the treadable region and the guide region. The transition area is configured to have one or more of a bend and a curvature and has an upwardly convex shape. | 10-16-2008 |
| 20150291186 | METHOD AND SYSTEM FOR DRIVE FOR SETBACK PLATFORM SYSTEM - Systems and methods for a shuttle platform that is configured to allow a path for one or more passengers to load or unload from a light rail transit vehicle that runs on a shared track. The shuttle platform can move in a linear plane and may be operationally engaged with a drive system comprising, a drive component and a combination position lock and drive mechanism disconnect. The drive component may comprise a transfer component. The combination position lock and drive mechanism disconnect may comprise: a drive disengage latch; a secondary lock latch selectably alternatively engagable between strikers; a manual drive receiver simultaneously operationally engagable with both the drive disengage latch and the secondary lock latch, and comprising a manual drive work output operationally engagable with the manual drive work input; and an automatic release. | 10-15-2015 |

| 20100251926 | Vehicle lifting apparatus - The present invention aims at providing an emergency staircase, whereby an operator can promptly and easily arrange the preparation of detrainment with the staircase in an emergency, and the passengers can detrain with a feeling of security. | 10-07-2010 |
| 20110088588 | AUTOMATIC LOCK FOR A MOBILE STEP MECHANICALLY CONNECTED TO A DOOR IN PARTICULAR FOR A RAILWAY COACH - An automatic lock for mobile steps ( | 04-21-2011 |
| 20150083023 | STEP DEVICE AND RAILCAR INCLUDING STEP DEVICE - A step device includes: a plurality of steps arranged so as to be lined up in a railcar width direction and constituting a part of a floor surface; and drive mechanisms configured to cause the steps to move upward and downward at a railcar-width-direction inner side between an upper position at which the plurality of steps become a part of the floor surface and a lower position at which the steps are moved downward to constitute boarding stairs. Each of the drive mechanisms includes a rotating link configured to rotate about one end portion thereof in a vertical plane, connecting links respectively connecting the rotating link to the steps, and an actuator configured to cause the rotating link to rotate. The steps move upward and downward by the rotation of the rotating links via the connecting links. | 03-26-2015 |

| 20140130707 | MOVABLE SUPPORT FITTING FOR RAILROAD CAR - An autorack railroad car has a housing surmounting an underframe. The underframe defines a first or main deck. The housing, or “rack” defines at least one additional deck spaced upwardly from the main deck. The housing has end doors. The end doors may be folding end doors, such as a tri-fold hinged door. When closed, the door may be secured by latches at top and bottom. The car may have a movable sill-step, or foot-hold that is movable between a deployed or extended position, and a stowed or retracted position. The movable step may be mounted to a panel of the door. The movable step may be biased away from any position between the stowed and retracted positions. The movable step may be free of springs that may break, and free of pins or other items requiring careful removal and replacement. The movable parts of the step assembly may be captured by the stationary parts to prevent them from coming loose or falling off. | 05-15-2014 |
| 20140352572 | HIGH LEVEL PLATFORM TRAPDOOR WITH BUILT IN MOVING SLIDE FOR RAILWAY PLATFORM GAP BRIDGING - A trapdoor assembly for use on railcars is provided. The trapdoor assembly is pivotable between an up position and a down position. In the up position, the trapdoor assembly provides access to stairs on the railcar so that passengers can egress between the railcar and a ground level platform at a rail station. In the down position, the trapdoor assembly covers the stairs and provides a platform so that passengers can egress between the railcar and an elevated platform at a rail station. The trapdoor assembly also includes an extendible platform for bridging the gap between the railcar and the elevated station when the trapdoor is in the down position and the railcar is stopped at the elevated station. | 12-04-2014 |
