Poland says Ukrainian citizens working for Russia are suspected of blowing up a railway line between Poland and Ukraine, the Prime Minister said the two suspects had been collaborating with Russian secret services for a long time.

the explosion on a rail line linking Poland’s capital, Warsaw, to the border with Ukraine happened over the weekend

In a separate incident, which Polish officials are also now confirming as sabotage, power lines over another segment of the same rail line further south were also damaged.

In the first incident, an explosion damaged the tracks near the village of Mika, about 100 kilometers (60 miles) southeast of Warsaw and, in a separate incident, power lines were destroyed in the area of Puławy, about 50 kilometers (30 miles) from Lublin. Trains carrying passengers were forced to stop at both locations, but no one was hurt.

But if you wanted to make a rail buggy, here's one guys easily portable design... just add quiet Honda portable generator, and an electric motor? I think you'd find it would be a nice quiet powered design. Add some gearing, and make it even faster.
