2017-4-1 TECHNICAL SPECIFICATION FOR SHOULDER BALLAST CLEANING MACHINE 1.0 GENERAL 1.1 These specifications are framed for a Shoulder Ballast Cleaning Machine (hereinafter called the machine), which should be capable of removing the ballast from the shoulder portion of the track, screen it, put back the screened ballast and profile it.
1 The contribution of base, crib and shoulder ballast to the lateral sliding resistance of railway track; a geotechnical perspective Authors: Le Pen and Powrie
This paper describes model tests used to investigate how ballast shoulder width and height contribute to a railway sleeper’s resistance to lateral movement for a range of shoulder widths and heights. Deflection and resistance were measured and photographs taken during the tests. The photographs were analyzed using a digital image correlation

2012-11-15 adequate lateral track stability with smaller ballast shoulder widths than those specified in Table 4.1. [8] The resistance to buckling forces may be enhanced by the provision of a ballast shoulder surcharge (windrow). [9] Use of the guidelines in this Clause will provide a design ballast shoulder

2019-1-21 5. SCREENING OF BALLAST Removal of the material from ballast to restore its voids is called screening of ballast. It may be shoulder screening, shallow screening or deep screening as the case may be, as decided as per extent of ballast fouling and maintenance problems. Screening of ballast is very costly and inconvenient work.
2019-7-10 platforms, tunnels etc.). The plough or ballast regulators may not be able to remove enough ballast, resulting in trains tripping. 4. DO NOT ballast over transom top bridges etc. Excessive ballast will result in ballast being ploughed into waterways or onto roads. 5. DO NOT ballast around train-stops, signals and track connections. 6.
2007-11-6 The shoulder is normally a 45 degree (1 in 1) slope. I presume this is an angle which the ballast holds easily but does not require excessive ballast to form. The trackbed and ballast itself is raised to provide natural drainage, which allows fines to pass through and keeps the ballast stable and cleaner.
2020-10-13 There are three major types of resilient elements used in rail tracks: (i) rail pads installed at the rail-sleeper (tie) interface, (ii) under sleeper pads embedded beneath the at the tie tie-ballast interface, and (iii) ballast mat placed underneath the ballast layer or at the s ballast/concrete interface in the case of a bridge deck.
2010-1-31 The minimum width of ballast shoulders that shall be provided is as follows: CWR straight track and curved track over 100 chains radius 15 inches. CWR curved track over 40 chains radius 18 inches. CWR curved track less than 40 chains radius and at insulated joints and expansion switches

On the other hand, shoulder height with an increment of up to 150 mm enriched the lateral resistance of the ballast track by 1.5 times by replacing the monoblock sleepers with biblock sleepers. Overall, it was proven that the interaction between crib ballast and sleepers has a more significant influence on the lateral resistance of the
