T-TRAK (all letters capitalized) is a modular model railroad system based on standards for module size, track placement, track interface, and electrical connections. The standards allow for a wide range of flexibility in design yet still maintain interoperability with all modules built per the standards.
The NMRA published alternative, more accurate and realistic standards for track and wheels sheet in S-1.1 These model railway standards are based on the full size prototype standards and the scale model operational reliability is therefore reduced in comparison to the models conforming to the normal NMRA standards.
NTRAK (all upper case letters) is one of several model railroad module standards. It is the most popular standard for use in United States N scale . NTRAK allows modelers to participate in a large layout but only invest a small amount of space at their own home.

The black portion around the labels is a metal back plate, painted a non-reflective black that labels were often affixed to, which was then mounted ...
Like the manual block systems outlined above, automatic systems divide the route into fixed blocks. At the end of each block, a set of signals is installed, along with a track-side sensor. When a train passes the sensor, the signals are triggered to display the "block occupied" aspect on the signals at either end of that block.
In many ways the VMEbus is equivalent or analogous to the pins of the 68000 run out onto a backplane.. However, one of the key features of the 68000 is a flat 32-bit memory model, free of memory segmentation and other "anti-features".
The 8-track tape (formally Stereo 8; commonly called eight-track cartridge, eight-track tape, and eight-track) is a magnetic-tape sound recording technology that was popular [2] from the mid-1960s until the late 1980s, when the compact cassette, which pre-dated the 8-track system, surpassed it in popularity for pre-recorded music.
