Increase in railway demand has significantly been met by rail operators through technological advances that have seen increase in train speed and axle loads, both to which have ensured an increase in operating capacity. However, from the infrastructure side, this has led to an increase in rail traffic demand that has been met with little extensions of rail infrastructure. Infrastructure managers (IMs) are faced with the challenge of having to increase the number of runs passenger and freight trains make across a relatively fixed network. This growing pressure on increasing operation time also reduces the infrastructure accessible time for maintenance activities.
