Rail operability

Rail operability relates to maintaining good technical conditions of the railway infrastructure, ensuring its safe and smooth operation. This term derives from the Railway Act (Railway Act No. 266/1994 Coll.). Providing rail operability is a crucial task for every rail operator. SŽDC is currently an operator of the national rail and most regional rails in the Czech Republic.
