Russia might bring ICBM on trains
 

Acourding to this article Russia has plans to bring back the missiletrains again.
The plans is to bring them back in the 2020s.

The new missile will be half the wieght of the old SS-24 missiles that once was used.

Russia to Bring Back Railroad-Based ICBM

God, I hope not. This is a spectacular waste of already limited funds.

Why do you think so?

Well this took me a while to see. Russia has more then enough ICBM projects on-going right now. The Topol family is still in production (including the Yars), the Avangard is a new ICBM, and apparently in addition to that a new liquid-fueled ICBM is planned. There's no need for yet another future ICBM project.

twise lighter is mean weight of yars and topol. strange that you not get it.

Why would the Russians want to go abck to liquid fuelled ICBMS.If i remember liquid fuelled missles took a long time to prep for launch and were vunerable to air attack when compaired to solid fuels missles were much easier to ready for launch.Plus Railway launchers are also vulnerable to attack by air (both on ther move and while stationary) and to special ops arids while being stationary.The truly protected missles in the Russian military are the slbms on board their remaing Typhoons and Delta-4 Subs.

The Topol family is pretty good too, given their mobility, and dispersion.

Also heavy liquid fuel missiles can carry much more in the way of penetration aids, decoys, etc. Finally bigger payload matters too. I don't know what the prep time for them is like.

An afterthought, train launchers might make some sense if they can use existing Topol family designs and simply mount them on train-TELs. Then they wouldn't need a new ICBM, just some adaptations to the launcher mechanism for railway travel. But I'm still not sure if it would offer any major advantage over regular Topol style TELs.

Then why stop on railway launchers, why not raid all their missile silos as well? As for the submarines, with that approach while having in mind US's supremacy in air thanks to all those aircraft carriers, one could also think that sub. capabilities could be reduced to zero as well because the submarines principal adversary is aviation.
In any case, it was originally thought that missiles launched from the moving trains were harder to track than stationary launches.
As for the liquid-fuel ballistic missiles, even though more expensive and complex to use than their solid-fuel counterparts, they can have bigger payloads, more electronic equipment necessary for suppression of anti-ballistic missile systems, as part of their payload etc.
