The phrase "alignment rail" is correct and usable in written English.
It can be used in contexts related to engineering, manufacturing, or construction, where it refers to a rail that helps align components or structures.
Example: "The technician adjusted the alignment rail to ensure that the machinery operated smoothly and accurately."
Alternatives: "guiding rail" or "positioning rail".
Kim et al. [22, 23] focused on vertical alignments between rail transit stations that exploited gravity to help accelerate and decelerate trains.
Although the now Erie-Lackawanna Railway continued to run the Montclair Branch, it reduced service, reducing the once two-rail alignment to one lone track, and removed most of the tracks at Lackawanna Terminal in Montclair.
A composite of employment and population densities, plus feeder service within ½ mile of the rail alignment, was made.
A spokesman for HS2 Ltd said: "Our contractors are undertaking a study looking at the effects of building a tunnel through Ealing compared with using the existing rail alignment next to the Central Line - taking into account the environmental impact and cost.
The developed method has been proven helpful to understanding the gap between transport supply and potential travel demand and the suitability of each node to alignment of each rail transit route through the PRD region case study.
The light-rail alignment along the Yongding River also would be designed to negate existing sources of stormwater runoff pollution and bolster the area's freshwater resources.
Following the engineering practice, this paper models the 3-dimensional rail track alignment with three separate components: the selection of stations, including station sequence and station type, the horizontal alignment that defines the track' path on the XY plane, and the vertical alignment that defines the elevation along the horizontal alignment.
The alignment of the light-rail line would follow a newly established rail corridor designed to be sensitive to local features of the natural environment, such as along the Yongding River near the Daxing airport and the Grand Canal near Tongzhou, where the light-rail corridor would be part of a riverfront conservation green corridor development.
The second objective is to maximize the ridership or the service coverage of the rail transit alignment.
A microscopic analysis is performed to develop a rail transit alignment in a given corridor considering a many-to-one travel demand pattern.
