This is simply not an issue for DC methods. AC systems have a selected basic safety line网页版下载 implication in the railway electrification system would work as a "Backdoor" link in between different pieces, leading to, amongst other matters, a bit in the grid de-energised for maintenance staying re-energised from your railway substation making Threat.
