Abstract: Remote objects, which may include cars and locomotives, rolling stock and or fixed objects in a model railroad layout, convey sound and/or other digital information to a Sound and Control Centers, Local Sound and Control Units and or walk-around throttles to produce sound and operations that enhances the model train experience. Preferably, remote objects may communicate with the sound and control center by wireless means, and over separate communication channels. Sound information and related data from the separate channels can be processed, combined, enhanced or used to fetch additional sounds from memory, in order to drive at least one speaker that is separate from the remote objects. The speaker(s) may be especially advantageous to produce or enhance low frequency audio sounds coordinated with activity at the remote object(s).

Abstract: A carpeting material of nonwoven synthetic thermoplastic resin fibers, capable of being folded so as to fit onto sharply irregular surfaces such as car trunk liners, made by the process of needle-looming a nonwoven carpeting material having higher and lower melting temperature synthetic thermoplastic resin fibers, subjecting the material to sufficient heat to soften and subsequently harden and rigidify one side of the carpeting, and then punching two substantially parallel rows of regularly spaced slots in the back side of the carpeting material. The slots of one row are arranged so that they are staggered in relation to the slots of the parallel row. The arrangement of slots in the back side of the carpeting enables it to be sharply folded while maintaining tear resistance.
