Depends exactly on what you want.
Start with the "Yellow Book" (see other posts on subject, downloadable; issue 4 deals now with maintenance), perhaps try to get hold of NR's GRIP = Guide to Railway Investment Projects (can't unfortunately post here) but that tends really to stop once system is in service.
Worth Googling for "Asset Management", "Reliability Centred Maintenance" etc; you won't find much strictly railway related but the concepts are similar in various industries (particularly those that have large complex and long lasting kit- e.g. power generation & distribution).
Of course don't just think about hardware; software may not be visible and it doesn't rust but that doesn't stop it requiring maintenance. A good book (but you won't have the time to devote to it prior to exam this year is Nancy Leveson: Software System Safety and Computers ISBN 0-201-11972-2).
Also have a read through past technical papers, Aspect conference papers etc. See the IRSE Exam Reading List for details and indeed I think some are on the Mod 1 Study Pack CD ROM.
