Soft sleeper

The Soft Sleeper (Chinese:软卧; pinyin:ruǎn wò), abbreviated RW or WR (CRH), is a passenger railway compartment class in the People's Republic of China. Soft sleeper is the main class on most Z-series express trains, and are grouped in several carriages as part of slower trains. They are more expensive than hard sleepers but are generally more comfortable as there is more room to move around and the bunks tend to be, albeit not always, softer in firmness. In many soft sleeper compartments, there is entertainment available through headphones connected to an LCD screen, although this is by no means universal.
