	Summary:
	In the hype of very ambitious plans for (re)construction of the BelgradeSubotica railway line, as well as of the entire key railway corridor thgough Serbia (former Corridor X), it is of essential importance not to forget that the railway lines are built of very long service lives (the oldest railway lines in the world are approaching the age of 200 years), during which the maintenance and renewal (M&R) costs of railway infrastructure elements (RIE) represent by far the largest part of expenditures, significantly larger than the initial investments, which may especially be true if all the phases of construction, from planning, via design, to construction and subsequent M&R are performed inadequately. Moreover, this fact is especially pronounced in case of high speed lines (HSL), which is exactly what, according to the current plans, the future Belgrade-Subotica line is supposed to be, due to several key characteristics that the HSL have in comparison to the conventional lines. It is therefore more than clear that it is of key importance, due to exremely large financial consequences during the entire service lives of such railway lines, that the Maintenance Concept, embodied by a Maintenance Design be immediately created together with the creation of all other Technical Design Documentation. Maintenacne Designs already represent for a number of years an inseparable constitutive part of the Technical Design Documentation elsewhere in the world, and serves to take into acount and foresee all relevant M&R aspects of all RIE. This article also puts an emphasis on the fact that the optimal manner of consideration of the Maintenance Concept for one particular railway line presupposes the definition of the general, global Maintenance Concept for the entire railway network in question (in this case of Serbian Railways), which this one line would represent but one constitutive part, or a corridor. Only this aproach can yield largest absolute benefits for the entire country, as the main investor that stands behind both the line to be constructed, as well as the entire railway network in question.
