Refuelling trains and locomotives brings its own challenges. When only a single engine needs refuelling,  then the system can be much the same as that used to fuel road vehicles, but when it comes to fuelling a long train, then the system needs to be able to co-ordinate the fuelling so that all sections of a set are fuelled without compromising accuracy or time.

Because of the spacing between pumps on a typical fuelling platform, individual fuel management systems are needed to control each pump and manage the fuelling, so keeping the cost of installation down is essential. The Jigsaw systems use GSM Mobile communications so there is no need to run communications cables to, and between the terminals. The Jigsaw system will operate with your existing pumps, usually without modification.

Railways Refuelling Systems

The Jigsaw system already has most of the UK rolling stock set up on it from other projects, but the part of that fleet that is allowed to fuel on your system will be set up against the site. As the fleet is assigned, groups are used to assign the TOC or operator of the train/loco so that billing for fuel is very much simplified.

Adding or removing fleet members is very simple as it is centralised through the web service - no need to upload vehicle lists to the individual fuel terminals.

On the Fuel Server :

Most Relevant Reports :

• Transaction listings by Group
• Period Stock reports
• Vehicle Group Fuel Usage

Relevant Vision Tiles :

• Site Throughput Growth Curve
• Group MPG Comparison
• Vehicle Highest Fuel Usage
• Driver Highest Fuel Usage
• CO2 Emission savings

• The Jigsaw system treats each unit in a train individually, but can also manage them as a set, comparing each individual unit with its peers - they travel the same distance, so they should take around the same amount of fuel - the Jigsaw system can easily highlight and units using more or less fuel than its peers.

Unique System Features :

• If Drivers cant be relied on to type in accurate mileages, then hardware may be fitted to the vehicles which will automatically gather and pass the mileage from the vehicle to the fuel island. Jigsaw Midas, FuelGuard and EasyFuel all have this option. Alternatively, if the vehicle is fitted with a tracking system, then some of these pass the vehicles mileage back to the telematics server. Jigsaw have interfaces to several telematics servers to recover this mileage automatically.
• Identifying the driver who fuelled the vehicle will enable the system to give you the tools to manage driver efficiency and misuse of company fuel. This can be achieved by issuing the drivers with personal ID tags.
• Many times a “Yard Key” is issued which is used to fuel visiting vehicles, contract hire vehicles and just about anything else - legitimate or otherwise. Plan for these eventualities by holding spare keys on site that can be issued and recovered as necessary. Alternatively the yard key can be replaced by a fueller tag or master tag where a valid registration number needs entering.
• It is common that a site is supplied from a trailer loaded with high pressure gas canisters. These are filled at another site where the gas is compressed. Make allowance for the control and monitoring of the gas filling point for these mobile stations.

Options to consider :

The Jigsaw system can integrate with a range of CNG, LNG and LPG  dispensers

Specific Features Developed for Train Refuelling

Railways

Jigsaw has a choice of train ID methods available; all three mentioned here are in use today on the UK Railway network :

Typed ID Entry. In this, the fueller first uses a personal ID tag on the system. The system then requests a typed vehicle ID. Both the fueller ID and loco’ ID are checked against a central database and fuelling commences.

FuelWand. In this, each locomotive/carriage is fitted with an ID tag which is scanned by the fueller using a small, robust, hand held reader. This removes the need for the fueller to type in the Loco ID, speeding up fuelling and reducing the possibility of misfuelling.

TeleTag. The Teletag system again uses a tag fitted to each Loco or Carriage to be fuelled, but the tag can be read from several meters away negating any requirement for the fueller to get involved in the ID process.

Identifying the Locomotive Units

Either the Eclipse or Nova may be used for train refuelling. The Eclipse can manage more than one pump so that, if required water or lubes could also be managed. All fuellings are logged by the system and passed immediately to the web service, so there is no need to collect and manage printed receipts.

If the fuel tanks are fitted with tank gauges, then they can be linked through the nearest pump control terminal so that the readings are passed to the web server on the back of each fuelling transaction, and a direct comparison between gauge and book stock may be made in real time.
