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]
In the example layout shown, trains take the left-hand track in their direction of running. Low-speed turnouts restrict the speed in one direction. Two platform faces are needed, and they can be provided either at a single island platform or two side platforms (as shown). Overtaking is not normally possible at this kind of up-and-down loop as ...
In any given country, rail traffic generally runs to one side of a double-track line, not always the same side as road traffic. Thus in Belgium, China, France (apart from the classic lines of the former German Alsace and Lorraine), Sweden (apart from Malmö and further south), Switzerland, Italy and Portugal for example, the railways use left-hand running, while the roads use right-hand running.
In regions where narrow-gauge lines form a small part of the rail network (as was the case on Russia's Sakhalin Railway), extra cost is involved in designing, manufacturing or importing narrow-gauge equipment. Solutions to interchangeability problems include bogie exchanges, a rollbock system, dual gauge, variable gauge, or gauge conversion.
Only 67 people voted in Lyman County — just over 6% of registered voters. Yet the county spent about $9,000 on ballot printing, hiring election workers and other costs.
As the threshold has been reduced, runoffs have become less common — and turnout has remained extremely low. This month, less than 3% of eligible voters participated in the second primary.
This circuit is monitored by electrical equipment to detect the absence of the trains. Since this is a safety appliance, fail-safe operation is crucial. Hence the circuit is designed to indicate the presence of a train when failures occur. On the other hand, false occupancy readings are disruptive to railway operations and must be minimized.
