Why is Russia attacking Ukraine's railways and are they failing?

Ed Arnold, European Security Research Fellow at The Royal United Services Institute, told Sky News that Russia faces difficulty hitting moving targets due to its weapon capabilities. "Russian attacks are unable to deliver a knockout blow to the rail network as they lack the availability of precision-guided munitions which are required to strike military targets. At best, they are only able to disrupt and delay rail movement, rather than prevent it," he said. "Unless Russia targets the network more extensively and with more precision-guided munitions, this will likely remain the case."
