Optical Fiber Sensor Design for Ground Slope Movement Monitoring for Railway Safety Operations (2018)
Presentation / Conference Contribution
Hook, D., Laing, W., Kerrouche, A., Barreto Gonzalez, D., & Alwis, L. S. (2018, October). Optical Fiber Sensor Design for Ground Slope Movement Monitoring for Railway Safety Operations. Presented at 17th IEEE SENSORS Conference, New Delhi, India

Scour and slope instability are a major issue in keeping the railway structures safe and operational. Conventional measurement techniques do not allow real-time monitoring of slope movement and/or are time/resource consuming. Novel fiber optic techno...

Drivers for vertical integration in the rail sector: using wagons as “relationship specific assets" (2016)
Journal Article
Monios, J., & Bergqvist, R. (2016). Drivers for vertical integration in the rail sector: using wagons as “relationship specific assets". International Journal of Logistics Management, The, 27(2), 533-551. https://doi.org/10.1108/IJLM-01-2015-0021

Purpose – This paper uses a combination of transaction cost economics (TCE), the resource-based view (RBV) and the relational view to analyse vertical integration in the rail sector, through which rail wagons are viewed as “relationship specific asse...

Machine vision approach for automating vegetation detection on railway tracks. (2013)
Journal Article
Yella, S., Nyberg, R., Payvar, B., Dougherty, M., & Gupta, N. K. (2013). Machine vision approach for automating vegetation detection on railway tracks. Journal of Intelligent Systems, 22, 179-196. https://doi.org/10.1515/jisys-2013-0017

The presence of vegetation on railway tracks (amongst other issues) threatens track safety and longevity. However, vegetation inspections in Sweden (and elsewhere in the world) are currently being carried out manually. Manually inspecting vegetation...

Rail Freight in Great Britain – has privatisation made a noticeable difference? (2012)
Presentation / Conference Contribution
Cowie, J. (2012, January). Rail Freight in Great Britain – has privatisation made a noticeable difference?. Presented at 44th Annual Conference of the University Transport Study Group

This paper briefly outlines the main changes brought about by the Railways Act 1993 with regard to the rail freight sector and then examines development of the sector since that time. It finds that although rail freight levels have increased, these... Read More about Rail Freight in Great Britain – has privatisation made a noticeable difference?.

Condition monitoring of wooden railway sleepers (2009)
Journal Article
Yella, S., Dougherty, M., & Gupta, N. K. (2009). Condition monitoring of wooden railway sleepers. Transportation Research Part C : Emerging Technologies, 17, 38-55. https://doi.org/10.1016/j.trc.2008.06.002

Wooden railway sleeper inspections in Sweden are currently performed manually by a human operator; such inspections are to large extent based on visual analysis. In this paper a machine vision based approach has been considered to emulate the visual... Read More about Condition monitoring of wooden railway sleepers.

Production economics of a vertically separated railway – The case of the British train operating companies. (2002)
Journal Article
Cowie, J. (2002). Production economics of a vertically separated railway – The case of the British train operating companies. Trasporti europei, 5, 45-52

This paper focuses on the production economics issues
surrounding the vertical separation of infrastructure
from rail services with regard to passenger operations. A
case study of the British passenger railway privatisation
is used. The British a... Read More about Production economics of a vertically separated railway – The case of the British train operating companies..

Continuous surface wave and impact methods of measuring the stiffness and density of railway ballast (2002)
Journal Article
Fairfield, C., & Zagyapan, M. (2002). Continuous surface wave and impact methods of measuring the stiffness and density of railway ballast. NDT and E International, 35(2), 75-81. https://doi.org/10.1016/s0963-8695%2801%2900034-2

Continuous surface wave and transient impact excitation tests were performed on strips of ballast to monitor their compaction. The ballast's shear wave velocity, hence the ratio of its shear modulus and density, increased with depth. Two types of tra...
