Wide provided suitable for busy trunk, also can be laid in tunnel and station floor maintenance difficulties, stone or soil subgrade are laid, but the mud pumping in the diseases of roadbed must be laid on the roadbed diseases after renovation. The main advantages of the wide sleeper circuit are: the suborbital sinking is small. The vibration acceleration is smaller than the concrete sleeper line, which gradually slows down and stops after laying. So the line maintenance work is greatly reduced, about a third of the general concrete sleeper line. The track is easy to keep clean. Dirt is not easy to break into the bed and prolong the repair cycle of the route. The line is smooth and stable, which is conducive to high-speed operation and the laying of seamless circuit. The disadvantage is that the cost is higher, and it is more difficult to change the shop on the busy trunk line

Its all-steel turbochargers certainly are a far cry through the ceramic ones positioned in their last Skyline GT-R release.
