205:) are more likely to be directional than those found on other continents. In Canada and the United States, the railroad often was built before other structures, and railway builders had much more freedom to lay down tracks where they wished. Similarly, when not constrained by space limitations many early Australian railways made use of wyes (particularly in rural locations) for their lower installation and maintenance costs; however, their necessity and use diminished from the 1960s onwards with the major trend in most states toward bidirectional locomotives and railcars.

There is a goods branch from
Chullora and, in the future, the possibility of a separate single track freight line. The three passenger stations at the vertices of the triangle have island platforms making it convenient to change trains. 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

They therefore have to be turned at the summit should it be necessary to make a through journey. Whilst limitations of space dictated that the triangle had to be partly constructed in tunnels it also ensures that in winter it is snow-free and thus readily available in emergencies.

There was insufficient space for a conventional triangle but this was overcome by constructing an "inside-out" triangle whereby the approach tracks intersected in a scissors crossing.

A typical use for a stub-end passenger station would be as follows: A wye was incorporated at the "throat" where the rows of tracks converged from the station to facilitate the turning of trains. An arriving train came to a stop on the main line after passing the wye. Once the switches on the wye are

Similar considerations as for mainline rail systems apply to the use of triangular junctions and reversing wyes on streetcar and tram systems.
