Abstract: According to some embodiments, a railcar comprises a railcar body comprising at least one end or side arranged in a generally vertical plane. The railcar comprises a staggered ladder coupled to the railcar body and extending in a generally vertical direction. The staggered ladder comprises a plurality of steps that are staggered such that at least one step proximate a bottom of the ladder is offset from the generally vertical plane of the railcar body by a greater distance than at least one step proximate a top of the ladder. The railcar further comprises a staggered handrail coupled to the rail car body and proximate the staggered ladder, wherein a bottom portion of the staggered handrail is offset from the vertical plane of the railcar body by a greater distance than a top portion of the staggered handrail.

Abstract: The present invention is directed towards a translation software that provides remote access to an application program that is executing on a host machine in its native operating system environment. The translation software monitors messages that are relayed from the application program to an application interface that is provided via the native operating system. Upon recognizing a message that affects a graphical user interface of the native operating system, the translation software converts the message into a protocol that is recognized by a remote graphical user interface. By monitoring and converting messages in this fashion, the translation software allows the application program to be displayed remotely.

Abstract: A special broadcast communication link is provided between a central processing unit and plural computer peripheral devices, the communication link being in addition to normal data and addressing communication lines, and providing a distributed control channel which is used to inhibit selected classes of interrupt signals from controllers associated with the peripheral devices in accordance with an interrupt classification system. This communication channel permits the central processing unit to issue a data command which selectively inhibits the peripheral devices from issuing selected classes of interrupt signals.
