2 CASE STUDY: Tyne & Wear Metro Nexus, the operators of the Tyne and Wear Metro approached us as they required the life span of their entire fleet of motors to last until The decision being whether to buy in new rolling stock or extend the life of the existing fleet. We offered HiTRAX, our insulation system proven to life extend DC and AC traction motors for over 10 years as a solution for the debilitated traction motor field systems. As a result, part of their 60 million reinvigoration process is now dedicated to rewinding the field systems on their entire fleet of motors with the HiTRAX system, resulting in their life span being extended to at least 2023 when new rolling stock will be introduced. 2 Houghton International Rail First class electro mechanical engineering services

8 DC LINE INDUCTOR MAINTENANCE & REPAIR In addition to the weather proofing programme for DC line inductors TOCs now have the option to repair rather than replace faulty units. This offers both a significant cost saving and substantially reduced lead times against buying new. WEATHER PROOFING Planned maintenance is proven to reduce in service failures and should be considered as part of your regular overhaul schedule. Weather proofing includes: Upgrade of caging to protect winding VPI for additional protection from the elements Application of sealant to protect against moisture ingress REPAIR our patented technical welding process for the repair of high current windings, repairs damaged line inductors and restores functionality. When a blast occurs, and the winding has been severely damaged by electrical short circuit arching in service, a weld process is applied to refurbish the damaged area, providing a high quality repair. Repairing, rather than replacing, can keep the inductor in service for years to come. We are the only company in the UK offering this service, it represents an opportunity to reduce costs and dramatically improve responsiveness when failure occurs. 8 Houghton International Rail First class electro mechanical engineering services

9 MECHANICAL & ELECTRICAL TESTING Traction motors sent to Houghton International for repair undergo a series of mechanical and electrical checks that are governed by the overhaul specifications Houghton International adhere to using a route card system. Route cards include an initial test and data report, assembly data report and test sheet and are populated at each stage of the repair process which highlights any defects that are present. Route cards are derived from the traction motor specifications to ensure product output is as required. The commutator profiles are carried out on receipt of the product, through each stage of the repair and also during the final inspection. The severity of the repair will determine the checks and tests conducted. For example, if an armature fails an electrical check and is deemed as requiring a full rewind, the new winding fitted will undergo several tests including pressure tests and resistance checks throughout the rewind process. An overhauled armature will not need to undergo the same checks as a fully rewound one as the checks that are specific to this situation are different. Route cards have specific job numbers and are cross referenced with product serial numbers to identify each product. Houghton International Rail First class electro mechanical engineering services 9

10 HST ALTERNATOR REPAIR Houghton International also offer an alternative to OEMs when it comes to HST alternator repair, potentially reducing costs and lead times. Our skilled engineers have worked on alternators in the marine and oil and gas industry for several years. This knowledge and experience can be utilised to give rail customers alternative options for repair. OVERHAUL Standard overhauls can be carried out alongside rigorous testing of all components. This includes a full rewind of all components from main stator to auxiliary exciter, using in house manufactured coils for optimum quality, performance and control. IN HOUSE AND IN SITU BAKER TESTING If you have a problem and cant diagnose the fault we will come to site and test your alternator in situ to help understand the issue, saving the time and expense of removing units that are not faulty. Independent of the OEMs, we have a strong culture of continuous improvement at Houghton International that allows us to be responsive to our customer s requirements and develop solutions to meet their needs. 10 Houghton International Rail First class electro mechanical engineering services

11 HiTRANS Our patented transient dynamic MA Set load testing process Many of our customers were experiencing major issues with their MA Sets. MA Sets were being returned from other repairers and failing almost immediately in service. As a result, we were asked to develop a solution that ensured every MA Set we repaired would work under full load conditions first time, every time. The result is HiTRANS, our patented (Protected by UK Patent No ) transient dynamic MA Set test process that electrically simulates full load conditions on any type of MA Set. It replicates exactly what happens in service, which means that the unit has been tested at full working load before it leaves our facility. The Benefits: Units work first time, every time Eliminates MA Set related in-service failure Proven life extension with HiTRAX insulation system Tests each MA Set through a dedicated controller i.e. FM2 Type Full load testing proves each individual wound component Reduced ongoing maintenance costs Reduced life-cycle cost Our repairs are proven to work first time, every time, and to a life expectation in line with the operating life of the train. We believe that we are the first company in the world capable of simulating exactly the electrical load conditions both through the MA Set controller and the incoming electrification.

12 CASE STUDY: Porterbrook Following reliability problems with traction motors, Houghton International were approached and asked to apply their knowledge and experience to fully evaluate the condition of some sample motors. The professional team at Houghton International assisted in the development of a comprehensive test regime which was augmented with a thorough physical examination of the component parts, drawing on the expertise of their suppliers and industry partners where appropriate. All test results were interpreted and presented in a clear and concise manner that ensured they were understood. The sound conclusions drawn from this investigation will be used to improve the future maintenance strategy for all Porterbrook traction motors of this type and Houghton International are a key partner in this on-going development work. Garry Taylor, Porterbrook Fleet Manager, London & South East This was a great example of FCC, Unipart Rail and Houghton International staff working together to understand the potential effect on our customers and putting together unique robust solutions that averted loss of availability and potential severe disruption to our customers. Ian Duncan, Head of Fleet GN CASE STUDY: First Capital Connect In February 2009 the UK witnessed one of its harshest snowfalls in the London region for over 10 years. As a result First Capital Connect (FCC) had over 40 traction motor failures due to earth faults. The implication of this was a shortage of vehicles. Once the initial impact was assessed, FCC approached Unipart Rail, who immediately involved their partner supplier Houghton International. A triage team was set up to assess the actual damage to each traction motor and the level of work required to bring them back to a serviceable condition. This also included Hornsey Depot s capacity to remove and refit the units and Houghton International s ability to individually assess each traction motor to determine whether it required major rework, such as an armature rewind or a light overhaul and dry out. In a matter of days, full availability of trains for passenger service was achieved. Within three weeks, quality, cost and delivery had been achieved. All defective motors had been removed, rectified by Houghton International and refitted to the vehicles. The drive, enthusiasm and flexibility of working together by all parties and not compromising any core values were greatly appreciated by FCC. 12 Houghton International Rail First class electro mechanical engineering services

13 Our traction motor life extension solution HiTRAX is an insulation system proven to extend the life of DC and AC traction motors for over 12 years. It is a combination of both our traction motor and high voltage expertise applied to solve the problem of deteriorating dielectric capability of problematic motors. Life extension can be required for numerous reasons; from poor original manufacturing processes and / or materials to, most commonly, degradation due to age, environmental exposure and transient voltages from inconsistent electrification. We understand that traction motors require special attention. They operate in unique conditions that expose them to heavy ingress of moisture and often corrosive dirt. Ambient running temperatures can range from -40 C to +50 C, and in humidity greater than 95%, providing maintenance issues to train owners and operators. Air intakes are often open to the elements, meaning snow and ice cause problems in winter periods, as do the leaves in the autumn. All contribute to the deterioration of a motor windings dielectric integrity. HiTRAX combines insulation materials that have the greatest dielectric durability throughout the wide temperature range traction motors are exposed to in their life cycle, with the highest specification VPI resins and stringent process control, tested to extremes. HiTRAX is proven to work in conjunction with both epoxy and silicone VPI resins, although we believe epoxy provides the absolute superior lasting protection. HiTRAX is proven because it has been running across the UK s rail system for longer than 12 years without failure. However, it is imperative that all elements within our total quality system are followed throughout the manufacturing, rewinding and VPI process for it to be absolutely effective. To date, we have never experienced a motor failure due to its insulation system. Houghton International Rail First class electro mechanical engineering services 13

14 I would recommend using Houghton International for any type of electric motor reconditioning. Phil Locke, Fleet Procurement Manager, Merseyrail CASE STUDY: Merseyrail Merseyrail were experiencing a 20% in-service failure rate for their G310 traction motor due to lack of product development work and required an urgent solution. We immediately added significant value by making small initial changes to the specification and introducing our HiTRAX system, the only insulation system in the world developed and marketed specifically into the rail traction motor market by a traction repair company. The improvements have reduced the Merseyrail in-service failure rate to under 0.02% and in 2012 Merseyrail suffered zero warranty failures on Houghton International serviced traction motors. 14 Houghton International Rail First class electro mechanical engineering services 14
