How the CD200 Accomplished an Impossible Task in Minneapolis, US
Rich Brawner, a field sales and product support specialist at Industry-Railway Suppliers is a railroad industry veteran with 41 years of experience. While visiting a Metro tunnel in Minneapolis MN, a seemingly unworkable problem proved that new technology can deliver advancements even veterans of the industry have never seen.
Over time, clips can become welded to the rail as a result of corrosion and other environmental influences. This was precisely the issue in a Metro rail tunnel, where steel Pandrol clips needed to be replaced, but could not be removed. For other machines, this was an impossible task. They were not able to remove or replace any clips. However, the Rosenqvist CD200 removed the clips without a hitch.
“I have never seen rail fasteners that were so attached to the rail,” said Rich, “I wasn’t sure what to expect since I was told that similar machines wouldn’t work at all. You could imagine the smile on my face when we started removing clips right off the bat.”
The ability from the machine is based on technology that allows the operator to place the pulling head anywhere in a 4” window around the clip, instead of the traditional competitions ½ inch. This allows the machine not only to grab faster, but also a wider range of grip on the clips.
Beyond a difficult few that needed to be aided with a sledgehammer, the majority of the clips were removed by just 3 to 4 cycles of the machine. Applying new clips had a 100% success rate. However, the situation showed the true manpower and teamwork the railroad takes.
“We all became laborers. We had to take a sledgehammer and lightly hit the clip holders to remove the massive rust that had built up,” Rich said, “After that, we had to take a broom and clean out the clip holders. Then we all set the new clips into position. Even with the 4% grade in the area, we were working, 2 of us were still able to push the CD200 back to the top of the hill to begin installing replacement clips. That was a CARDIO work out.”
“I believe there isn’t a job this machine can’t handle,” Rich said, “Even those on site agreed it was exactly what they needed to get the job done.”

Pandrol’s New Alpha Rail Grinder
Training on RCI System
Pandrol offers training on the RCI system at the time of delivery of a rail-converted excavator. RCI (Rated Capacity Indicator) is a load, height and slew limitation system. The use of RCI is specified in the EN15746 European standard, which is gradually being implemented throughout Europe.
The RCI training at Pandrol contains both theoretical and practical parts. Recently operator Anders Hjort, operator at Bergs Gräv AB in Sweden recieved training on how to operate their new rail-converted Volvo EWR150E on the Pandrol test track.
Pandrol also offers training for new operators who haven’t used an RCI system before. For more information, please contact us at email@example.com or phone +46 650 16505.
Efficient Sleeper Change
RailCom AS in Norway has recently carried out a sleeper replacement project for Banenor AS. The project took place on the weekend of 21-21 September at Brottum Station on the line between Hamar and Lillehammer and included installation and removal of sleepers and changing 1800 concrete sleepers with Pandrol FE fastenings. RailCom AS who have a long experience of these types of projects had planned the work carefully, which resulted in all of the 1800 sleepers being replaced the same day in a matter of 15 hours. The work was done with 4 road rail machines equipped with the Rosenqvist sleeper changing attachment SB60. The SB60 units were equipped with the Automaster attachment, which is operated from the cab and easily installs the FE clips on the sleeper.
The new sleepers had been placed along the track beforehand, using the Rosenqvist sleeper laying unit SL400. The project supervisors Mikael Eriksson and Tom Andersson at RailCom AS say that an efficient sleeper replacement program requires thorough planning and management of the work process. And it of course requires skilled machine operators, of which RailCom AS has plenty.
We design, develop and manufacture equipment to make constructing and maintaining railways more efficient. Our smart machinery increases productivity, reduces possession times and improves the safety of those working in the industry.
