We were going to try that in the early 60’s with Minuteman missiles. Not sure why we didn’t get past the design stage.
Wasn’t it part of the MX concept too?
Lionel’s was successful. They’ve been selling them for years.
Securing thousands of miles of railroad track is tough to do, and if you fence it all off then you’ve just got one big military reservation as a target.
Likewise, unsecured railroad track is perhaps *not* the best place to be transporting live, road-mobile nuclear weapons.

Placing nukes onboard subs gives them the ability to range over 70% of the planet undetected. Any rail-based system it going to be limited to the installed track and difficult to conceal. Seems like it would also be a lot more difficult to secure the area around a rail-based ICBM from attack.
