TRACK TECHNOLOGY


Pioneering solutions to railway engineering problems


Gordon Suthorn, business development manager at Swietelsky International (UK & Ireland), discusses the company’s latest track mounted railway engineering technologies.


S


wietelsky was formed in 1936 and has grown into one of Austria’s leading construction


companies with group offices and operations spread throughout mainland Europe as well as the United Kingdom. Swietelsky’s Rail Division is a leading provider of track construction, maintenance and renewal including the supply, operation and development of highly specialised on-track technologies.


The division owns and operates a fleet of over 500 high performance rail-mounted machines, specifically designed and built for works on all types of railway networks. Swietelsky’s fleet contains several world firsts, including the mighty RU800-S, the first combined high output ballast cleaning and track relaying machine, followed later by the PM1000-URM formation rehabilitation system, which remains the most powerful track mounted machine ever constructed.


World firsts


The RU800-S delivers completely new track in a single operation, making it the most efficient ‘track renewals factory’ in the world. The RU offers huge savings over conventional methodologies, reducing reliance on multi- machine technology to deliver the renewal of the entire track system. Lower unit rates are achieved by reducing the number of track possessions required to deliver the same work and reducing transport costs of mobilising equipment by half in relative terms.


The PM1000-URM is a 1,000 ton machine capable of processing over 1,300m3


of excavated


material per hour from a cut dimension up to 7m wide and 1.5m deep. The PM1000 advances at around 120m/hour, rehabilitating up to 1,400m of track per day with the adjacent line open to traffic. This represents an output increase of around 50% over other systems with less disruption.

Swietelsky’s current typical annual volume of track infrastructure related delivery:


• Track relaying – 1015km • Track formation rehabilitation – 276km • Track ballast cleaning – 344km • Turnout replacement and renewal (including ballast) – 475 units

• Rail grinding – 724km • Turnout grinding – 1200 units


• Renewals tamping, lining and stabilising to design – 5200km


• Maintenance tamping, lining and stabilising to design – 7500km


• Flash butt welding – 4000 No. • Track design – 2800km


The company uses market leading design and technology to drive ever more efficient track construction and rehabilitation processes, improved recycling capability and vastly reduced disruptive impact to railway networks.


Indeed, Swietelsky’s work at the forefront of these technologies has produced a number of ‘System Swietelsky’ designs (including the RU and PM) which were developed especially for and in conjunction with Swietelsky.


High Speed Solutions for High Speed Rail


In addition to the above, Swietelsky owns and operates a series of complementary machines specifically designed and built for work on high speed lines, including: • 09-4X – the highest output plain line tamping technology available. • 09-32/4S – the most advanced S&C tamping system available. • BDS 2000 – the complete ballast management system.


• APT 1500 R – the advanced flash butt welding and rail tensioning system.


Supporting their larger counterparts or working independently, these machines form a comprehensive offering from Swietelsky, perfectly suited to technically demanding and disruption-sensitive high speed routes.


Support


The company’s international railway engineering works are supported by its world class maintenance, overhaul and workshop facilities centred in Fischamend (Austria), ensuring optimised availability and reliability of the equipment.


Swietelsky also owns RTS; an expanding rail haulage business with a fleet of over 40 locomotives and more than 800 wagons deployed across mainland Europe.


RTS provides haulage solutions to a range of client organisations and supports Swietelsky’s own railway engineering operations.
