Ballast is the description for the aggregate beneath the rail track. The track ballast forms the track bed that suports the rail track load and provides water drainage. Rail ballast aggregate is typically 30-50mm aggretate. Hard and tough stone is required for rail ballast. Resists the severe attrition in a railway trackbed environment.
When railways began to pay more attention to ballasting their roadbeds in order to accommodate faster and heavier trains, there was a need to distribute ballast on the sides of the track as well as between the rails. This was why the Hart-Otis Ballast Car was invented. Ballast is the gravel or rock that is used to keep the railway ties in place.
Jun 01, 2020 Bhusawal – Akola rail section is located in Central India as shown in Fig. 3(a). In this section, the track superstructure consisted of pre-stressed concrete sleeper (PSC-6), 60 kg/m rail with the ultimate tensile strength of 90 kg/mm 2 and elastic fastenings systems (rail pad, metal liners and rail clips) (IRPWM, 2004).In 2012, the track management system (TMS) was introduced to retain ...
Railway ballast used in construction should comply with all the requirements of this European Standard. The standard includes comprehensive and specific requirements for natural aggregates and recycled ballast, dealing with, for example, the stability of certain basalts. For materials from some other secondary sources, however, work is ongoing ...
Ballast refers to the gravel or crushed rock paved on the road or railway subgrade, it is mainly used in railway subgrade.

The ballast is then given a wash of well-thinned brown enamel to weather and tone it down, the effect is quite subtle, further coats could give dirtier track but this seemed enough for sidings. The sleepers had been dry-brushed with grey before ballasting, and of course the rails given a dirty rusty brown colour, resulting in a pleasing track ...
