Transnet Capital Projects – Northern Cape
Leading railway signalling specialists ACTOM Signalling successfully completed a major contract for Transnet Capital Projects in the Northern Cape recently.
The R90-million contract, which consisted of replacing the old blockworking system on the 200 km section of the line between Postmasburg and Kamfersdam station near Kimberley, was commenced in September 2011 and completed two months ahead of schedule in October 2012.
“The old copper cable based system had been in operation for close on 50 years. Our task was to replace it with a modern optical fibre cable based blockworking system, involving installation of modern axle-counter equipment incorporating failsafe data transmission (FSDT) and upgrading the existing CS90 remote control system to accommodate the new axle-counters, while also interfacing the new system with the old interlocking system that continues to operate at all the stations,” explained Gerrie Coetzer, ACTOM Signalling’s Contracts Manager.
“Among the various difficulties we faced were a very tight schedule for completion of the first half of the project, logistical problems arising from the great overall distance covered, as well as punishing working conditions, with temperatures rising to as much as 40 degrees C at times, and tough trenching conditions in places.”
The contract required completion of 50% of the work within 10 months of commencement. “This part of the contract, between Kamfersdam and Koopmansfontein, was extremely fast track and very challenging, but we completed it on time,” Coetzer commented.
The full distance covered by the contract was about 200 km, of which 86 km required trenching.
“The long distances involved necessitated deployment of three separate complete working teams, each comprising trenching, cable-laying and installation personnel, with two testing teams to serve the three sections,” Coetzer explained.
Some of the sites presented extremely rocky trenching conditions – particularly at Barkly West, UlcoGhaap and Limeacres. “Another complication we faced was at the start of the contract between Kamfersdam and Macfarlane, where the line was under water due to flooding from Kamfersdam Dam, which had overflowed onto the line. This forced us to postpone occupation there until the end of the contract period,” he added.
No lost time injuries were incurred throughout the contract. “On completion of the first half of the contract Transnet Capital Projects presented us with a 100 000 hours lost time injury free award,” Coetzer concluded.
