Turnouts facing and trailing. Note that this diagram is for left-hand traffic; for right-hand traffic, "F" and "T" would be swapped. Facing or trailing are railway turnouts (or 'points' in the UK) in respect to whether they are divergent or convergent. When a train traverses a turnout in a facing direction, it may diverge onto either of the two ...
Additionally there is a switch on the right hand joystick to operate attached tools. The most commonly used control pattern throughout the world is the ISO controls. In the ISO control pattern, the left hand joystick controls Swing (left & right) and the Stick Boom (away & close) , and the right hand joystick controls the Main Boom (up & down ...
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.
A facing turnout is used to prevent any unauthorised movement that may otherwise obstruct the main line. [1] The trap points also prevent any damage that may be done by a vehicle passing over points not set for traffic joining the main line. [2] In the United Kingdom, the use of trap points at siding exits is required by government legislation. [2]

Full service reduction A brakeman uses a fusee to demonstrate a hand signal indicating "stop" The maximum air pressure that can be exerted against brake pistons in a normal brake application. To increase pressure beyond this ...
"Right-in" and "left-in" refer to turns from a main road into an intersection (or a driveway or parcel); "right-out" and "left-out" refer to turns from an intersection (or a driveway or parcel) to a main road. [1] [2] [3] RIRO is typical when vehicles drive on the right, and LILO is usual where vehicles
A good ground resistance is 5–10 ohms which can be measured using specialist earth test equipment. SWER systems are designed to limit the electric field in the earth to 20 volts per meter to avoid shocking people and animals that might be in the area. Other standard features include automatic reclosing circuit breakers . Most faults ...
Track circuits allow railway signalling systems to operate semi-automatically, by displaying signals for trains to slow or stop in the presence of occupied track ahead of them. They help prevent dispatchers and operators from causing accidents, both by informing them of track occupancy and by preventing signals from displaying unsafe indications.
