Railcar-launched ICBM
A railcar-launched ICBM is an intercontinental ballistic missile that can be launched from a train. The first operational example, and the best-known, is the Soviet RT-23 Molodets. The United States planned and started development of an analogue, the Peacekeeper Rail Garrison, but abandoned the plan with the end of the Cold War. Similar system was tested by China in 2016. North Korea also planned to create a railway-launched ICBM.
