A right-hand railroad switch with point indicator pointing to right Animated diagram of a right-hand railroad switch. Rail track A divides into two: track B (the straight track) and track C (the diverging track); note that the green line represents direction of travel only, the black lines represent fixed portions of track, and the red lines depict the moving components.
The goods siding on a double line (in the above diagram) uses two trailing points and a diamond. It can be shunted by trains in either direction. This was widely done in New South Wales, though later on the diamond crossing was replaced with a pair of ladder crossovers; such as: Bredalabane (S) Jerrawa (S) Woy Woy (N) Newbridge (W)
A single tongue trap consists of only one switch rail, leading away from the main line to a short tongue of rail. This is usually placed in the rail farthest from the main line. Double trap points are a full turnout, leading to two tongues. Usually the tongue nearer the main line is longer than the other.
The sharp curves of the triangle, and especially the turnouts on those sharp curves, restrict train speeds to between 10 and 50 km/h (6.2 and 31.1 mph). Near Hamilton station on the Central Coast and Newcastle line there is a wye for freight trains and regional trains. This puts them directly on the Main Northern line.
Gauntlet tracks can be used to provide horizontal clearance to a fixed obstruction adjacent to a track such as a cutting, bridge, or tunnel.Frog gauntlets are also commonly used when a rail line's capacity is increased by the provision of an additional track, but cost or other factors prevent the widening of the bridges.
It consisted of a full system including locomotive decoders (based on a Motorola chip), central control, a computer interface, turnout decoders, digital relays and s88 feedback modules. For controlling 2-rail DC locomotives, like Märklin's Z and 1 gauge rolling stock, a special version of the system was introduced in 1988 developed by Lenz ...
The line to neutral voltage is half the line-to-line voltage. Lighting and small appliances may be connected between a line wire and the neutral. Higher-power appliances, such as cooking equipment, space heating, water heaters, clothes dryers, air conditioners and electric vehicle charging equipment, are connected to the two line conductors.
Leaf valve: one-way valve consisting of a diagonal obstruction with an opening covered by a hinged flap; Line blind valve: a thin sheet oriented perpendicular to the pipe. The sheet has a solid end and a flow-through end; sliding it from one position to the other opens or stops the flow. Also called sliding blind valve
