This is a bit ironic given the fact that Russia makes a conscious choice to rely on railways for military logistics. Why? Because they are more resilient and easier to repair than roads - Russia has railroad engineering units in their military and can repair just about anything you could do to a railroad in a couple of hours, and in fact they do as Ukrainian partisans (rightly) go after railways. Meanwhile if someone throws spike strips on a busy highway/tunnel/bridge between two chokepoints, you're effectively screwed. If this is done in a concerted manner it will probably take at least a day to fix. If you have more resources (say a state actor attacking a nation that isn't on a wartime footing), you can also exploit the fact that asphalt is a petroleum fraction and therefore soluble : spill a lot of diesel or hydraulic oil, for example (and optionally set it on fire) and you will unrecoverably ruin that section of asphalt, which could take weeks to fix: this is why gas stations are paved with concrete. So while it's not as easy to do this as it is to derail a train or screw around a signaling system, it's far more difficult to repair professional roadway sabotage than railway sabotage, and in the end the railways are probably more resilient.
