Recent changes in the cost and availability of natural gas (NG) as compared to diesel have sparked interest at all levels of the commercial shipping sector. In particular, Class 1 heavy-duty rail has been researching NG as a supplement to diesel combustion. This study investigates the relative economic and emissions advantage of making use of the energy efficiencies if combustion is circumvented altogether by use of fuel cell (FC) technologies applied to NG. FC technology for the transport sector has primarily been developed for the private automobile. However, FC use in the automobile sector faces considerable economic and logistical barriers such as cost, range, durability, and refueling infrastructure. The heavy-duty freight sector may be a more reasonable setting to introduce FC technology to the transportation market. The industry has shown interest in adopting NG as a potential fuel by already investing in NG infrastructure and locomotives. The two most promising FC technologies are proton exchange membrane fuel cells (PEMFCs) and solid oxide fuel cells (SOFCs). SOFCs are more efficient and capable of accepting any kind of fuel, which makes them particularly attractive. The rail industry can benefit from the adoption of FC technology through reduced costs and emissions, as well as limiting dependence on diesel, which accounts for a large portion of operation expenses for Class 1 railroads. This report provides an economic feasibility analysis comparing the use of PEMFCs and SOFCs in heavy freight rail transport applications. The scope is to provide insight into which technologies could be pursued by the industry and to prioritize technologies that need further development. Initial results do not show economic potential for NG and fuel cells in locomotion, but some minimal potential for reduced emissions is seen. Various technology configurations and market scenarios analyzed could provide savings if the price of LNG is decreased and the price of diesel increases. The most beneficial areas of needed research include technology development for the variable output of SOFCs, and hot start-up optimization.

This paper reports on an action research project based in the UK rail industry; it used a novel type of Soft Systems Methodology (known as PrOH Modelling) to facilitate change in a major Train Operating Company (TOC). The project looked at a number of different disruptive incidents to compare and contrast practice via the Mitigate, Prevent, React and Recover (MPRR) Framework. One incident is detailed in depth. The paper also looks at the general process of conducting action research. This work will be of interest for researchers in the rail sector and for those conducting operations action research projects.

Diplomityön tavoitteena on selvittää rautatiealalla toimivien yritysten turvallisuuden hallinnan nykytilaa ja löytää keinoja sen parantamiseen. Tutkimuksen kannalta olennaisia teemoja ovat turvallisuuskulttuuri, turvallisuusjohtaminen ja turvallisuusvaatimukset. Työ tarkastelee rautatiealalla toimivia Liikenneviraston palveluntuottajayrityksiä ja heidän näkemyksiään turvallisuuden hallinnan nykytilanteesta edellä mainittujen teemojen ja työn teoriatutkimuksen avulla. Työn teoriaosuus esittelee laajasti rautatiealalla vallitsevia sääntöjä, määräyksiä, ohjeita ja standardeja. Näiden vaatimusten lisäksi teoriaosuus esittelee rautatiealan turvallisuusjohtamisjärjestelmää (TJJ), joka jaetaan turvallisuuden hallinnan osa-alueiksi. Näitä osa-alueita käytetään apuna tunnistettaessa rautatiealalla toimivien yritysten kannalta tärkeimmät turvallisuuden hallinnan osa-alueet. Työn empiirisessä osuudessa toteutetaan haastattelututkimus rautatiealalla toimiville yrityksille. Haastattelujen perusteella tunnistetaan turvallisuuden hallinnan kannalta tärkeitä kehittämiskohteita ja toimivia käytäntöjä turvallisuuteen liittyen. Näiden avulla luodaan kuva turvallisuuden nykytilasta, joka esitetään työn turvallisuusteemojen avulla. Työn tuloksena esitetään malli viidestä, rautatiealalla toimivien yritysten näkökulmasta keskeisestä, turvallisuuden hallinnan osa-alueesta. Mallia soveltamalla rautatiealalla toimivat yritykset pystyvät vastaamaan paremmin turvallisuusvaatimuksiin, kehittämään turvallisuustoimintojaan ja lisäämään koko yrityksen tietoisuutta turvallisuudesta rautatieympäristössä.

This paper reports on a current research project in which virtual reality simulators are being investigated as a means of simulating hazardous Rail work conditions in order to allow train drivers to practice decision-making under stress. When working under high stress conditions train drivers need to move beyond procedural responses into a response activated through their own problem-solving and decision-making skills. This study focuses on the use of stress inoculation training which aims to build driver’s confidence in the use of new decision-making skills by being repeatedly required to respond to hazardous driving conditions. In particular, the study makes use of a train cab driving simulator to reproduce potentially stress inducing real-world scenarios. Initial pilot research has been undertaken in which drivers have experienced the training simulation and subsequently completed surveys on the level of immersion experienced. Concurrently drivers have also participated in a velocity perception experiment designed to objectively measure the fidelity of the virtual training environment. Baseline data, against which decision-making skills post training will be measured, is being gathered via cognitive task analysis designed to identify primary decision requirements for specific rail events. While considerable efforts have been invested in improving Virtual Reality technology, little is known about how to best use this technology for training personnel to respond to workplace conditions in the Rail Industry. To enable the best use of simulators for training in the Rail context the project aims to identify those factors within virtual reality that support required learning outcomes and use this information to design training simulations that reliably and safely train staff in required workplace accident response skills.
