Rail freight transport is a key economic activity; many businesses and people rely on it. It should be available when needed and efficient in use. There are however factors that may reduce the availability and quality of a rail freight service offering. A distinction can be made between what may be called systemic factors, like congestion, accidents and technical failures, and external factors like weather conditions and natural disasters. Rail infrastructure managers and users of rail services have learned from experience to anticipate or adapt to systemic factors. They are, to some extent, also able to cope with certain weather conditions. A rather different situation occurs when the weather becomes more extreme and less predictable. Water management systems are usually not developed for excess amounts of rain and hence will fail. Terrestrial water can turn into a devastating flood that may (temporarily) incapacitate railway infrastructure. With this (partially) out of service, freight trains have to be rerouted. This may lead to severe delays, additional costs and externalities, in particular more emissions. This paper deals with the question: What are options for governments to make rail freight transport more resilient to disruptions triggered by climate change, while limiting the externalities caused by rerouting? The paper is an extension of earlier research on this topic. Methods used in the research were a case study, the data of which were fed into a simulation model, which was used to estimate route length, fuel consumption and emissions. The main outcome of the study is that there are interesting options to make rail freight transport networks more resilient. In order to reap their benefits, interoperability should be improved considerably.

Road transport offers important logistic benefits at a reasonable cost for producers and consumers, hence its large market share. But, its use of diesel or gas generates large volumes of Co2, nox and pm10 (among others). Higher emission standards and demand for greener transport call for alternatives. literature analysis, a simulated Dutch-german road trip and a partial financial analysis are used to compare different engine-fuel combinations. Electricity from green sources removes these emissions. To stimulate full electric trucks (FET) several issues need to be addressed. First is creation of a large charging network. The netherlands is much further with this than germany. Affordability is another one. operating and investment costs should at least equal those of non-FET to have comparable total cost of ownership (TCo) over the lifetime of a truck. with FET, investment costs are now much higher, which should be compensated by lower operating costs. The actual operating costs depend on many factors, but fuel costs and trip time are likely to rise if en-route recharging is needed. A more in-depth financial analysis is needed for more exact conclusions. Another issue is technical. practice tests are needed to enhance the results of the simulation study. Hybrid diesel-electric and FET are already used in urban and regional transport. Regulation should also become tighter. Zero emission should become the norm. if these issues are successfully death with, then electric drive will become the mainstream technology. Technically, 2025 or 2030 seem feasible for large-scale production, which also lowers investment costs. with more electricity needed for transport, the supply of green electricity should grow strongly. Finally, the micro simulation is a modest example of the potential of the simulation model. modeling of other corridors is underway, using one truck or a fleet of FET.

Overland transport of goods mainly goes by road. Road freight transport, trucking in particular, has a large share in the energy consumption, CO2-emissions and air pollution by human activities. This will become an even bigger issue with the expected massive growth of road freight transport.
Climate change mitigation asks for a major reduction of CO2-emissions from human origin. Improvement of air quality is a second reason why trucking companies have to look for alternative engine-fuel configurations: Biodiesel, gas and electricity. The paper answers two research questions:
1.New truck technologies are under way, what impact could these have on fuel consumption and emissions related with the fuel consumption of trucks?
2.How realistic is large-scale introduction of these new technologies before the year 2030?
A model was used to estimate the emissions of CO2, NOx and PM10 of a truck transporting goods along a pre-defined route consisting of city roads and highways. The volumes and composition of the emissions vary depending on the data entered by the user: Route/distance, fuel efficiency/consumption, emission factors and engine-fuel configuration. The model was used for a micro-simulation, but an extension towards a macro-simulation model is feasible. This would allow to estimate the impact on fuel consumption and emissions for a fleet of trucks. The model indicates that the main benefit of an alternative like biodiesel lies in the reduction of PM10-emissions. Electric trucking is necessary to drastically reduce CO2-emissions and air pollution.
In a few years from now hybrid diesel-electric trucks will become common. Full-electric trucks energized by internal (hydrogen in fuel cells) and/or external (trolley-like, high density batteries) sources are feasible well before the year 2030. Electric trucking means a drastic change in the use of fuels with implications for the electricity grid as well.
