The American Society of Civil Engineers (or ASCE) specified rail profiles in 1893 [20] for 5 lb/yd (2.5 kg/m) increments from 40 to 100 lb/yd (19.8 to 49.6 kg/m). Height of rail equaled width of foot for each ASCE tee-rail weight; and the profiles specified fixed proportion of weight in head, web and foot of 42%, 21% and 37%, respectively.
This article provides a list of operational and under construction (or approved) high-speed rail networks, listed by country or region. While the International Union of Railways defines high-speed rail as public transport by rail at speeds of at least 200 km/h (124 mph) for upgraded tracks and 250 km/h (155 mph) or faster for new tracks, this article lists all the systems and lines that ...
These include simple rail adhesion, rack railways and cable inclines (including rail mounted water tanks to carry barges). To help with braking on the descent, a non-load-bearing "brake rail" located between the running rails can be used, similar to the rail used in the Fell system, e.g. by the Snaefell Mountain Railway on the Isle of Man.
All the early French railways (including Saint-Etienne Andrezieux, authorised 1823, opened 1827) had a French Gauge of 1,500 mm (4 ft 11 + 1 ⁄ 16 in) from rail axis to rail axis, compatible with early standard gauge tolerances) Dublin and Kingstown Railway: 1831: 1834 For passenger traffic: converted to 5 ft 3in Newcastle & Carlisle Railway ...
For example, North America uses the reference rail as the line rail which is the east rail of tangent track running north and south, the north rail of tangent track running east and west, the outer rail (the rail that is further away from the center) on curves, or the outside rails in multiple track territory.

RailTopoModel is a systemic data model for describing the topology-based railway infrastructure as needed by various applications. The RailTopoModel has been initially developed under patronage of the International Union of Railways (UIC) and was released as International Railway Standard (IRS) 30100 in April 2016. [1]
Mairie de Loevenich (), from the Topographic Survey of the Rhineland by Tranchot/Müffling, sheet 57 (published 1806/07).. A map series is a group of topographic or thematic charts or maps usually having the same scale and cartographic specifications, and with each sheet appropriately identified by its publisher as belonging to the same series.
The NMRA published alternative, more accurate and realistic standards for track and wheels sheet in S-1.1 These model railway standards are based on the full size prototype standards and the scale model operational reliability is therefore reduced in comparison to the models conforming to the normal NMRA standards.
