Railroad bridge question

[jchnhtfd]

Probably Erie... but I couldn't tell you which one, just off hand.

Yes, there are counterweights. For all their size, those things are so well balanced that it takes very little power to move them (some swing bridges still in use on CP and CN are moved by hand!). The rail alignment when they come back down is managed by engaging the movable portion of the rail with a kind of a grooved fitting in the stationary part (swing bridges are quite different). It is a little like a switchpoint, but not quite. They are complicated and a maintenance headache beyond belief.

Will need a New York-area expert to tell you. Judging by an older SPV atlas it is near the "Bergen Arches" (ex-Erie) or the "Bergen Tunnels" (ex-Lackawanna). Since there is no catenary, does it make this route the ex-Erie?

I posted this over on the MR board maybe somebody knows here.

Anybody know what bridge is pictured on page 39 of March 2005 Trains? It looks like quite a bridge and would be interesting to know more about it. It would and really interesting model to take a swing at kitbashing.

Also, anybody know how they work? Counterweights? How does the track line up when they set it back down?

Thanks!
