Abstract
The economical effect of an investment strategy in railway signalling is defined
by the costs and revenues generated by the chosen system over its lifetime.
While the cost positions relevant for an infrastructure manager can all be
expressed in the performance figure Life Cycle Costs (LCC), only part of the
revenue positions can be expressed monetarily. Therefore, it is necessary to also
include non-monetary revenue positions when deciding on which railway
signalling system to choose. Since most of the cost and revenue positions are
closely linked to the system operation, the idea of using information from
railway operation simulation software has been evolved. The Institute of
Transportation Systems has therefore implemented a software link between the
simulation software RailSys and a new developed Cost-Benefit-Tool. With the
latter the relevant life cycle cost and revenue positions of the evaluated signalling
system and scenario can be captured, calculated and analysed. This simulationbased
evaluation of investment strategies for railway signalling is part of the
RAILONOMICS concept. RAILONOMICS enables infrastructure managers
to develop efficient investment and maintenance strategies in a structured
manner.
Keywords: railway signalling, investment strategy, railway operation simulation,
