Pulling trains out of Hudson River tunnels?

I always like hearing Manhatan Transfer brougt up. Mr West has detailed its location quite nicely along with photos. What I still find interesting is that there are still remnants of the demolished platforms - lots of left over bricks alongside the tracks.

Thanks Drewh. The drawings show concrete perimeter walls on piling, concrete sub floor and then buff bricks on edge for surfacing the platform out to granolithic finished concrete edge strips. Now we know exactly how far the demolition crew went to dispose of the bricks!

Railway Age Jan 15, 1938 has a story on removing the H&M eastbound bridge here. It was a double track through truss, 222’ long and weighed 1000 tons. To avoid disrupting the busy main it was jacked up, the southeast end set on a swing bridge bearing and at the northwest end small bridge girders taken from the approach spans were placed on pile bents to make a falsework path along an arc over the mainline. This was paved with rails for skidding rollers to run on. A couple of 80 ton power screw jacks then took turns pushing the n/w end along this temporary span all the way to the south side in 12 hours. There they could support the bridge in sections while they unpinned its joints and scrapped it. This method was considered safer than dismantling the bridge on falsework over the mainline tracks and avoided dragging out the scrapping work with pauses every time a train came through.
