A double junction is a railway junction where a double-track railway splits into two double track lines. Usually, one line is the main line and carries traffic through the junction at normal speed, while the other track is a branch line that carries traffic through the junction at reduced speed.

A grand union is a rail track junction where two double-track railway or tramway lines cross at grade, often in a street intersection or crossroads. A total of sixteen railroad switches (sets of points) allow streetcars (or in rarer installations, trains) coming from any direction to take any of the three other directions.

Double-track railways, especially older ones, may use each track exclusively in one direction. This arrangement simplifies the signalling systems, especially where the signalling is mechanical (e.g. semaphore signals).

2023年4月30日 · Track junctions are created by the combination of points and crossings. The main function of track junctions is to transfer the train from one track to another or to facilitate the crossing of trains from one track to another. There are different types of track junctions depending on the traffic requirements.

2021年6月2日 · Start at the right side, creating a side track from the OUTER track (the topmost), making sure you're clicking the grass at least once (building in two segments) to connect it to the rightmost track at the top.

A double junction (Fig. 15.17) is required when two or more main line tracks are running and other tracks are branching off from these main line tracks in the same direction. The layout of a double junction consists of ordinary turnouts with one or more diamond crossings depending upon the number of parallel tracks.

2019年4月16日 · This document discusses various types of track junctions and simple track layouts used in railway engineering. It defines turnouts of similar and contrary flexure, symmetrical splits, three-throw switches, double turnouts, crossovers, diamond crossings, scissors crossovers, gauntleted tracks, gathering lines, triangles, and double junctions.

2019年1月1日 · I can get one rail to cross a doubletrack cleanly, see the Tips and Tricks, but I can NOT get the second rail of a double track to cross the other double track simply next to the first track of that double track.

Connect a single track curve to your existing double track somewhere. After confirming the build, you will see a smaller cone on the opposite line. This is the point to connect to when doubling the curve you just built.

Junctions are formed at any point where a piece of railway track directly crosses or joins another piece. In OpenTTD, references to junctions are almost always talking about rail junction because the other modes of transport either do not need them or they are trivial to build.
