You do get deniability though. Given their line is "this is malicious code that was put on the train. Physical security is the responsibility of the train companies”, they would argue the fact their binaries are different is proof of malicious actors.
Essentially, if they're going to do this, a good route is for them to be the malicious actors. Just before shipping, someone trusted surreptitiously switches the binaries to the modded versions.
