Ballasted Track versus Ballastless Track Szabolcs Attila Köllő1,a, Attila Puskás1,b and Gavril Köllő1,c 1Faculty of Civil Engineering, Technical University of Cluj-Napoca, C-tin Daicoviciu no. 15, 400020, Cluj-Napoca, Romania Romania akszabolcsattila@yahoo.com, b*attila.puskas@dst.utcluj.ro, cgavril.kollo@cfdp.utcluj.ro Keywords: Rail superstructure, rail supports, concrete sleeper, ballasted track, slab track, stability, maintenance.
Mainly the increase of speed and axle load has forced the railway construction engineers to try finding other solutions in this topic.
This improvement shows also that due to the accumulated experience with ballasted track the engineers are more confident to deal with ballasted track issues.
Initially, in this aspect, the slab track structures had a great disadvantage compared to the ballasted track system, but due to the modernizations with the rail fastening systems, engineers have already created satisfactory vibration and noise absorbing structures.
