Road still carries about 75 per cent of all Europe's freight.
The total tonnage carried by rail and other modes has gone up but so has road freight, so the proportion each carries has remained about the same.
While bulk freight can be transported by rail or sea, market demand in the freight industry will dictate how customers want their goods moved.
The market has continued to decide which form of freight to use, rather than incentives and tax breaks.
Improvements to rail infrastructure in Europe have resulted in only small increases in rail freight carried, so rail has been reluctant to make large capital expenditure, because the returns are not there.
The same is likely to apply to New Zealand.
Road freight will always be preferred for any perishable goods because it can carry out the task faster — apart from much more expensive air freight.
Road freight has greater service quality — quicker door-to-door delivery times and greater safety with less chance of damaged goods, which usually occurs when the freight is changed from one mode to another.
Even when rail or sea is used, trucks are often needed to get goods to the rail hub or sea port to start the journey and pick them up to make the final delivery.
Highly competitive costs within the road freight sector make it more appealing to customers than the alternatives.
Road freight has flexible route choices. Rail and sea do not with only a few fixed routes.
Road freight will nearly always be used for the "last miles" as customers want door-to-door delivery.
Rail is only generally better when the type of goods (very large or non-urgent) can be shipped by train instead of road. This occurs when a customer places all their business with a road freight operator who then decides the best way to ship it to meet deadlines or budget.
Improving New Zealand's rail services and infrastructure will be taxpayer funded and subsidised.
Improvements in road freight transport — newer fleet with cleaner emissions, less noise — are paid for by the trucking companies and their customers.
Rail will only ever handle a small proportion of the country's total freight as 90 per cent of road freight is done within metropolitan/urban areas where rail and sea are not an option.
With the increased investment in the rail sector, KiwiRail remains a commercial operating arm of the Government.
This is likely to require rail price increases to cover the investment costs, closing the gap between road and rail pricing, making the latter less attractive to freight customers.
