2.0 The Role Of Light Rail Transit In Edmonton's Transportation System 2.1 Definition and Description of L.R.T. The platform's height cannot exceed 4x its base width without additional stabilizing support. Refer to Figure 5.2 for platform zones and width details. Given arrival and departure times of all trains that reach a railway station, the task is to find the minimum number of platforms required for the railway station so that no train waits. Examples: Input: arr[] = {9:00, 9:40, 9:50, 11:00, 15:00, 18:00} The platform width was derived as follows: • 3.5 metre clearance zone from the edge of platform to any structure. Railway Technical Website Page 2 Updated 10th May 2017 track itself is supported on "ballast", made up of stones - usually granite or, in the US, basalt - below which is a … Access may also be railway platforms at the station precinct. OSHA 1910.23(e)(1)(vi): The maximum work-surface height of mobile ladder stands and platforms does not exceed four times the shortest base dimension, without additional support. The French train operator SNCF has discovered that 2,000 new trains it ordered at a cost of 15bn euros are too wide for many regional platforms. FIGURE 5.2 –PLATFORM ZONES AND WIDTHS Minimum platform widths are as follows: (1) Marginal platforms – single or dual tra ck Within this category, there are also issues about platform height and materials. The width and length of the platform is dictated by the location and the operational needs of Metra. 2. Measure to transit stop pole at near-side, or rear of transit vehicle at far-side. Over and under bridges located mid-platform were generally assumed for passenger circulation and platform access, and were designed to manage the maximum number of people carried by the longest train (300 metres). Copings are manufactured in full accordance with the requirements of NR/L3/CIV/030 and are accredited as conforming to the pendulum … Platform access is affected by the location of the station buildings, the type and size of the platform, and the location of the parking lots. FP McCann is an approved manufacturer and supplier of platform copings to Network Rail and London Underground specifications. 5. Platform Heights (above rail height): 2.4mm – 380mm platform as found in small stations (<25 trains a day) 3.5mm – to represent 550mm platforms 4.8mm – for 760mm platforms found in the large stations 6.0mm – 960mm S-Bahn station platforms (just a guess, Sydney Stations too) 8.0mm – for goods / loading ramps The minimum side clearance for platforms, eight inches or less above the top of the rail, shall be four feet eight inches. We are given two arrays which represent arrival and departure times of trains that stop. Locate platform with at least 10 feet of clear distance from crosswalk or curb return. Rail platform length will vary based on vehicle length, but should extend from the front door through the rear door.
