No. I never saw a train run on top of another train either.

I don't think it was laying it's own track, but replacing the ties beneath the track.

Either way, it was defiantly cool.

It did look cool.
If the concrete ties aren't reinforced properly when they are made, there is trouble

The MBTA filed a lawsuit yesterday against the manufacturer of crumbling ties on the Old Colony commuter rail lines, demanding that the company reimburse the T for an estimated $91.5 million replacement project and pay other costs and damages.

The faulty ties, barely a decade old, have hampered travel on the Old Colony Line’s Plymouth/Kingston and Middleborough/Lakeville branches and forced the T to impose speed restrictions. The full replacement project for all 147,500 ties on those branches is scheduled to begin this summer and last nearly two years, imposing significant delays and disruptions for thousands of riders between Boston and its southern suburbs.

It looks like the T could use this machine for their project.

Wanna see how it used to be done?
