 2- Scope and description of the supply  
The name 3D&FAT, refers to a Train Derailment Detection and Automatic Braking Device and as its name suggests, it is a system installed in a towed railcar or goods or freight wagon o passengers (hereinafter referred to wagon) with bogies. It is meant to detect derailment of any of its wheels at the very instant when it takes place, immediately and automatically causing the entire train to brake. Thus the 3D&FAT system is not capable of preventing or avoiding derailment of the train and is activated only when a derailment occurs. The Seller declares that if the system is correctly installed and the device is maintained in good working condition, when a wagon equipped with the 3D&FAT system derails, the device will be capable of detecting the same in the majority of circumstances, converting this fact into a pneumatic signal transmitted to the brake valve, to immediately cause the train to brake, regardless of its speed.   
The 3D&FAT may not act (or act not reduce damage) in certain accidents, such as: overturned in a curve, both speeding and low speed (excessive camber), bridge collapse, landslide and/or detachment lands, frontal, side or rear shocks. In general, any cause (such as hurricane side winds, earthquakes, tsunamis, etc.) that destabilizes the wagon, if there has not been previous derailment.
The 3D&FAT system comprises the following elements:
  • Two self‐actuating bells, one for each bogie.
  • Two position detectors or switches, one for each bogie.
  • One brake valve, for each wagon.
  • One pneumatic connection system  
  • Supports and fastenings for the unit.
The scope of the supply only includes:
  • A technical study, which shall be done by specialized technical staff, according to the conditions specified in Chapter 4. A specific study is required for each wagon type. The Contract must indicate for how many different types of wagons customisation of the 3D&FAT system will be done.
  • Component parts of the 3D&FAT system, corresponding to each wagon (unless indicated otherwise in the contract: two position detectors or switches and one brake valve).The number of wagons for which the system is being supplied shall be indicated in the Order or Contract.
  • Assembling Instructions and Maintenance Manual.rato.
  • Transfer of Operating Licence, according to the conditions established in chapter 3, of this G.C.S
Consequently, the scope of supply does not include:
  • The required piping for interconnection between the elements supplied, assembling of the same and their brackets.
  • Valve of closing or isolation, threaded sleeves, Tes and its grafts in TFA.
  • Metallic brackets to fix the position detectors or switches on the wagon body.
  • Fixing of the bells (preferably soldered) to the bogies.
  • Assembling and commissioning of the 3D&FAT system on each of the wagons.
  • In general, the scope of the supply does not include any element or service that is not specifically indicated in the preceding section or in the Contract.
  • Optionally, ARS can separately offer and charge for, bells, closing valve, pneumatic connection system and  “in situ” training of the staff appointed by the Buyer to assemble the initial wagons, according to the conditions specified in chapter 5. 
3- Operating Licence. Rights and obligations of the Buyer   
The 3D&FAT system, is a patented product and has industrial property protection. It was invented and developed by the railway staff of Feve (at present integrated into Adif‐Renfe). The scope of supply includes purchase by the Buyer of the constituent elements of the 3D&FAT system, defined in Chapter 2 and the award of an Operating Licence that authorizes the Buyer to use the 3D&FAT system, for an indefinite period of time, provided that it faithfully complies with the conditions stated in this chapter.
The said Operating Licence authorizes the Buyer to:
  • Install or assemble the number of 3D&FAT systems supplied by the Seller, in an equal number of wagons owned by the Buyer.
  • Use the 3D&FAT systems, installed as indicated in the point above, as train derailment detection and automatic braking devices.
  • Obtain spare blocks from the Seller, at the listed price, to provide for any accidents that may damage the ones installed.
  • Technical assistance from the seller, in any derailment episodes that take place in the future.
The Operating Licence does not authorize the Buyer in any way to:
  • Copy or reproduce any of the components and/or blocks constituting the system supplied.
  • Dismantle internally or tamper with any of the components and/or blocks that constitute the system supplied.
  • Under no circumstances, transfer, lease or sell any of the components and/or blocks constituting the system that has been sold, to third parties. Third parties shall be considered as any person or entity (both commercial and non‐commercial), including subsidiary companies, investee companies or having a share in it or in the Buyer’s company
As a consequence of the above and to maintain the validity of the Operating Licence transfer, the Buyer undertakes and is obliged to:
  • Inform the Seller, before commissioning the system, of the registration number of each wagon on which the system has been installed. It shall also inform of any subsequent changes that may take place.
  • To hand over damaged or unserviceable blocks to the Seller, regardless of the cause, when these are dismantled and regardless of whether or not they have been replaced by other new ones.
  • Inform the Seller of recorded derailments, indicating where they took place, speed of the train, composition of the train (engines and number and type of loaded and empty wagons), type of loads transported, place occupied by the derailed wagon and whether or not it had the 3D&FAT system installed and in running order, distance covered by the train between when the derailment started and when it stopped, assessment of damages to rolling stock and to the track structure... That is to say, as much information as possible to study the behaviour of the system. The Seller undertakes to use this information, only statistically and undertakes to keep the source of information confidential. 
  • Maintain confidentiality with respect to the Assembly and Maintenance Instructions.
  • The Seller on its own, through its Representative or any person or entity expressly authorized by it, can freely inspect whether or not the conditions specified in this document and/or agreed upon in the Contract have been met.

Based on prior information provided by the Buyer (normally in the form of responses to the questionnaire sent by the Selling Party) the Seller, shall conduct a Technical Study, according to the corresponding order, in order to evaluate the possibility of adapting 3D&FAT system to the type/s of wagons that the Buyer owns and design the required elements to ensure its proper functioning.    The number of different Studies to be conducted will depend on the number of different models or bogies that are part of the Buyer’s fleet. The Seller is only obliged to conduct the Study or Studies that are agreed upon in the Contract, and the costs incurred on account of new inclusions shall be borne by the Buyer.   The 3D&FAT system should not be installed in wagons for which the corresponding Study has not been conducted beforehand. The Seller declines all responsibility if the Buyer does not comply with this requisite, whether intentionally or not.
