TMCC utilizes the same command codes as Digital Command Control (DCC). However, unlike DCC, it uses a 455 kHz radio transmission to carry the command codes separate from track power. The locomotive decoders are dependent on AC track power (50 or 60 Hz) to synchronize the command receiver. Thus, TMCC can only operate on AC track power.
The point machine (in this case an electric motor) and associated mechanism used to operate this switch can be seen to the right in the picture. A point machine (also known as a point motor, switch machine or switch motor) is a device for operating railway turnouts especially at a distance.
Märklin Digital was among the earlier digital model railway control systems. It was a comprehensive system including locomotive decoders (based on a Motorola chip), central control (Märklin 6020/6021), a computer interface (Märklin 6050), turnout decoders (Märklin 6083), digital relays (Märklin 6084) and feedback modules (Märklin s88/6088).
Klein was a bicycle company founded by Gary Klein that pioneered the use of large diameter aluminium alloy tubes for greater stiffness and lower weight.. Klein produced his first bicycle frames while a student at the Massachusetts Institute of Technology during the 1970s, and full production runs of frames began in the 1980s.
A compound DC motor connects the armature and fields windings in a shunt and a series combination to give it characteristics of both a shunt and a series DC motor. [5] This motor is used when both a high starting torque and good speed regulation is needed. The motor can be connected in two arrangements: cumulatively or differentially.

These engine kits were designed or marketed by both small and large companies, including Bike Bug, Tas Spitz, and even Sears, which sold the Free Spirit, and Little Devil engine kits. Most of these kits were designed to use lightweight, low-cost two-stroke engines from Japanese manufacturers such as Tanaka. During the late 1990s, the arrival of ...
