Road/Rail Excavator the Komatsu PW170ES. By Mick House.

This article was first published in our CRS magazine on the 15th June 2011.
The Komatsu PW170ES is a road/rail excavator a smaller bit of plant, but just as important as its larger rail bound brothers. This machine number 444 (picture 01) is the Komat`su PW170ES owned by Quattro, it has a 3.92 litre, 91 KW, 121 horse power at 2200 RPM 4 cylinder, direct injection, turbo charged, intercooled Komatsu SAA4D102-E2 diesel engine (what a mouth full!). The engine powers a hydraulic pump incorporated in HydrauMind Komatsu’s unique hydraulic system. In the HydrauMind system, the load sensing valves and pressure compensated valves automatically handle all adjustments for individual work applications based on the pressure and lever stroke they sense. The machine has a 250-litre fuel and 135 litre hydraulic oil tanks.
It has fully automatic transmission with permanent 4-wheel drive and three travel modes: High mode 0 to 30.0 km/h, Medium mode 0 to 10.0 km/h and Low mode 0 to 3.5 km/h all in forward or reverse. It is 8.26 meters long (27.126 feet) and 2.5 meters wide (8.2 feet). When in travel mode, it has a maximum reach of just over 9 meters, can work to a depth of just over 5 meters and rotates a full 360 degrees.
These machines have rail guidance fitted to enable them to travel on the railway. They can travel at the same speeds as on the road but will be restricted to line speeds governed by Network Rail, for example on rail a maximum working speed of 2.41km/h (1.5MPH). Komat`su do not fit rail guidance wheels to their machines as standard, these are fitted by independent company’s like Quattro plant and Rexquote. This Quattro version is also fitted with a quick release mechanism and lifting hook (picture 02) to enable it to fit different attachments to it operating arm. Attachments with this machine on the day were a sleeper grab (picture 03), a ballast bucket (picture 04), a thimble which enables the rail to move through itself as the machine is lifting rail in to position (picture 05) and also a four wheeled rail trolley (picture 01) that it tows along. Other attachments that can be incorporated into these machines are ballast brushes, rail cutters, rotary cutters, tamping banks, flails, ploughs, steel sleeper grabs, profile buckets, rock breakers, grabs, lifting beams, access platforms, ripper teeth, augers, vibrating plates and many more. Around the time of its visit, the machine was engaged in the replacement of individual sleepers and ballast in the area.
As an up date to this article sister machine number 467 was in Truro yard on 18-04-2012 and it had been modified with disc brakes on the rail guidance wheels to allow it to tow greater loads on rail, (picture 06) shows a before modification shot and (picture 07) shows an after modification shot. It has also been fitted with extra ballast weight (picture 08) to enable it to lift heavier loads, this is the black rectangular box situated under the second step and stretching across the underside of the machine.

Network Rail Measurement Train Rolling Stock (part 4). By Mick House.

We see a number of Network Rail Measurement Trains visit our area over the years and predominantly the photos that have been taken are of the Locomotives that bring the trains down, but what of the rolling stock that is within the train! Most of the vehicles you see are ex passenger carrying coaches or vehicles that have been used for other railway duties. I have put together a selection of these vehicles as I feel they do not get enough recognition. Words & photos by Mick House.

Mobile Flash Butt Welder
By Mick House.
This article was first published in our winter 2012 Magazine.
Extra photos have been added to this article.

Another trip to Truro yard, and we have a Flash Butt Welder (take those thoughts right out of your head this is a clean magazine).
ATMW 751 All Terrain Mobile Flash Butt Welder (picture 01) developed, operated and run by Future Welding Limited (UK) is a Doosan Solar DX160W wheeled excavator machine fitted with Philmor Rail (UK) rail guidance (picture 02) and Holland K-922 welding head and Deutz rear-mounted power pack and Generator.
The DX160W wheeled excavator machine with Double cab. It has a Doosan DL06 “Common rail” 6-cylinder direct fuel injection electronic controlled diesel engine, it is water cooled, and turbo charged with air-to-air intercooler and is 128 HP at 2200 RPM with a travel speed 10 - 37 km/h (6 – 23 mph), Operating Weight is 15,300 kg (32,408 lb) without the welder and power pack.
Rail guidance is by rail wheels mounted on axles with hydraulically operated rams that engage the wheels on to the track when the machine is in position over the rails, when in position the rams are locked.
The welder (picture 03) has a working voltage: 380 to 480 volt ± 10%. Primary current: 540 amps, welding current: 30,000 amps, working pressure in hydraulic system: 207 bar (3000 psi). clamping force: 320 Tons (290 metric tons) this is the force used to grip the two rail to be welded, upset / pull force: 132 Tons (120 metric tons) this is the pull exerted on the two rails to bring them together for welding, welding / pulling stroke: 150 mm (5.9 inches) and a weight: 3100 kg (6,834lbs). The welder also has a Paton Pulse process allowing for shorter weld time, less welding material, less surface area of heat and 90% fewer defects in the finished weld giving a uniform hardness.
The rear-mounted power pack and Generator is a Deutz V6 diesel engine 322 – 670 hp at 1900 - 2100 rpm with Marathon Electric Magnaplus Generator.
The machine is able to operate in a 360 degrees radius with a reach of 5.91m (19ft 4in) from its centre on or off rail. It is also able to work under live overhead line equipment and can perform up to 12 welds per hour.

The Fugro`s, Rila and Rail-Map solutions.
Words and photos by Mick House.

Network Rail had awarded RailData a subsidiary of Fugro a contract for survey and design works to support its High Output Track Renewal Programme for 2016-17.
Fugro is a company based at Leidschendam in the Netherlands. They have developed and are the world’s largest integrator of geotechnical, survey, subsea and geosciences services. Among they’re various systems RailData has Rila; this is for use in railway application. RailData will apply its train-mounted Rila system to deliver highly accurate rail infrastructure information with additional ground survey services provided by UK-based Severn Partnership. This approach will enable a phased and controlled transfer from conventional survey methods to advanced train-mounted systems to deliver the information critical to track renewal schemes and will deliver significant health and safety benefits to Network Rail by greatly reducing the requirement for survey personnel to be on or near the track during the collection of survey data and also allowing trains to run safely on adjacent lines, minimising disruption to services.
This system can record and take in data at a speed of 160kph (99.4mph). The system is a portable platform that can be mounted on the front or rear of a locomotive or train its only requirements are a power supply and laptop connection. The system is mounted on the buffers of the train/loco with clamps and a safety wire to the draw/gedge hook and can be installed by two men in a matter of minuets; they also travel with the system to record and monitor it via the laptop. The system has two GPS navigation pods mounted on top, a laser array at the bottom, and a six head camera in the middle, just below that are two 3D giros.

The Fugro’s, Rila system at the time the photos were taken, was travelling through Cornwall, mounted on a Colas class 70 810 and Class 66 850 (David Maidment OBE), I have also photographed it on Colas 66 847.
