A "Drop in Boomerang" is designed to mount into the color slot of a lighting fixture and provide the operator with several manually selected gels. Most often this accessory is seen in conjunction with the followspot yoke , when a fixture is being used as a small replacement followspot .
The tough metal tracks with discreet cardboard sleepers was indication of Fleischmann's objective, and was the base for the perfected track line used in layouts today. In conjunction with the track, and a full assortment of accessories for the model railroad layout , H0 tycoons were presented with a class 01 tender loco, a class 80 tank loco ...
The field angle of an instrument is the angle of the beam of light where it reaches 10% of the intensity of the center of the beam. Most manufacturers now use field angle to indicate the spread that the fixture has. However, older fixtures are described by the width of the lens x focal length of the instrument. For example, a 6x9 ellipsoidal ...
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.
Model railway scales and gauges are standardized in NEM 010, [1] which covers several gauges for each scale. Narrow gauges are indicated by an additional letter added after the base scale as follows: no letter = standard gauge (1,250–1,700 mm or 49.2–66.9 in) m = metre gauge (850–1,250 mm or 33.5–49.2 in)
