ACO’s TramDrain Manages Stormwater for Australian Light Railways

Light rail is an increasingly popular choice of transport in Australia. Not only is it a highly desirable means for travel for many Australians, but compared to traditional railways and buses, light rail travel is a quieter, smoother and often a more time and energy  efficient ride for commuters. Additionally, as higher volumes of commuter traffic are catered for, the operational costs per customer are comparatively low.

In light of rapid economic growth and development in both urban and rural areas, these factors have recently driven strong interest from politicians and planners as they strive to make public transportation systems sustainable and effective.

One key consideration of this new infrastructure is how it deals with rain. According to Railway Substructure.org, emphasis needs to be placed on how water is managed. A crucial element is that track installations do not add complication to the runoff and disposal of storm water. To be effective they must “intercept and redirect lateral storm water” (Railway Substructure, Rail Wiki, chapter 4.7.4.4.1.). This not only prolongs the life of the track but minimises the effects that water runoff can have on adjacent footpaths, roads and around building thresholds.  

Linear drainage systems are essential solutions for the water management of track infrastructure. These vital systems must be specifically developed to suit grooved rail and track slabs in light rail environments. For instance, whilst the drain needs to be in contact with the rail for drainage, all metallic drain elements (grates, bolts etc...) must be isolated from stray currents in the tram rail. This is a key requirement for this type of drainage.

Track drains must also have the ability to be adapted for bespoke applications. A tram line’s drain performance is not the only criteria. Drain grates are in constant visual and physical contact with the urban environment and so grate aesthetics must also be taken into account. Additionally, not only are small slotted grates recommended to protect heels but these metallic elements must have a degree of slip resistance. Ease of access for maintenance is also critical if drains are to be kept functional for the design life of the project. Read More...
