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. 363:
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

Trains normally descend in the direction they have arrived from and are designed accordingly with the power unit at the lower end and seating angled to compensate for the gradient. 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. 1656: 1530: 1385: 1580: 1036: 352: 1750: 1616: 1540: 1448: 1441: 1283: 1174: 1169: 1681: 1608: 1562: 1142: 1080: 685: 1598: 1590: 1572: 1481: 1466: 1456: 1431: 1377: 1198: 661: 1714: 1691: 1673: 1554: 1547: 1513: 1368: 1342: 1335: 1328: 1276: 1269: 1250: 1242: 1224: 1158: 1150: 1132: 1091: 1020: 1758: 1742: 1733: 1698: 1666: 1648: 1624: 1522: 1473: 1409: 1395: 1234: 1124: 1100: 1013: 1489: 1402: 1216: 1206: 1028: 1349: 155: 1980: 29: 895:. Eventually authority was given to construct a turning arrangement on a strip of spare land to the west of the main line, just south of Grantham station. 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. 923:
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

in 1837. The triangle has two passenger platform faces on each of its three sides and five of the six platforms are in frequent (half-hourly, etc.) use by passenger trains. When steam engines were in regular use the triangle (which is of course also traversed by freight trains) was also used to turn

The land within a triangle is cut off from the adjacent area (and normally fenced off) and has marginal commercial value, so will be purposed mainly for the railway's exclusive use – generally being used for maintenance depots, storage, or vehicle parking. On electrified lines substations tend to be

Similar considerations as for mainline rail systems apply to the use of triangular junctions and reversing wyes on streetcar and tram systems. Many, although by no means all, streetcar and tram systems use single ended vehicles that have doors on one side only, and that must be turned at each end of

Meanwhile, the locomotives could be uncoupled from the train and sent to the engine terminal to be serviced for their next assignment. Then, the head-end cars could be uncoupled from the rest of the train and spotted by a station switcher at the parcel facility where mail and express packages were

A triangle may have a situational disadvantage in train operations when space constraints of the local geography cause one leg of triangle to bypass a main station. In tight city environments, this can happen easily, as it did, for example, at

The former allows direct Limerick–Dublin passenger trains to bypass the Limerick Junction station, and is also occasionally used to turn steam locomotives on railtours, whilst the latter is used primarily by freight trains running between 550:. Though two sides of the former are still in mainline use, the "back line" between Monkstown and Greenisland has been removed, whilst the latter was closed altogether in 1957.
