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)
Diagram showing the use of trap points to protect the main line at the exit of a siding An insulated track circuit interrupter fitted to trap points. Trap points are found at the exit from a siding or where a secondary track joins a main line. A facing turnout is used to prevent any unauthorised movement that may otherwise obstruct the main ...
A swingnose crossing at Bonn Hauptbahnhof Swingnose crossing at a switch set for the diverging line A swingnose crossing or moveable point frog is a device used at a railroad switch to eliminate the gap at the common crossing (a.k.a. frog ) which can cause damage and noise.
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.
Railways in Nigeria consist of a 3,505 km Cape gauge national railway network and 669 km of standard gauge. The Cape gauge network is in poor condition due to lack of maintenance. In 2019, the single operational standard gauge line from Abuja to Kaduna generated as much revenue as the entire Cape gauge railway network combined. [1]
The five-track railway line just south of Kursky Terminal is crossed through a narrow tunnel built at the beginning of the 20th century and unsuitable for a two-track tram line. Other similar stretches were removed or re-organised, since according to the standards, gauntlet tracks on tram lines are only permitted as a temporary measure. [ 14 ]
Hornby Railways Zero 1 was a forerunner to the modern digital model railway control system, developed by Hornby in the late 1970s. It was based around the TMS1000 four-bit microprocessor. The Zero 1 system enabled the simultaneous control of up to 16 locomotives and up to 99 accessories such as points and signals.
