Railway transport is capable of high levels of passenger and cargo utilization and energy efficiency, but is often less flexible and more capital-intensive than road transport, when lower traffic levels are considered.
Transportasi kereta api mampu mengakomodasi arus penumpang dan barang yang tinggi dan efisiensi energi, tetapi sering kurang fleksibel dan membutuhkan banyak modal daripada transportasi jalan, ketika tingkat lalu lintas yang lebih rendah dipertimbangkan.
