There is little double-tracking and average train speed is still low. The heavy
haul railway, high-speed railway, and the operations management systems are at
an initial stage, to be improved. It is known that six hundred container freight
stations exist (Zhu et al. 2010). However, many are reconstructed from ordinary
cargo stations, and therefore equipment or facilities are not very appropriate for
containerized freight. Moreover, these container stations may not be located at the
best sites.
