Riding MTB over Railroad (bridge) Viaduct

Recently rode one of my Mountain Bikes over into Pennsylvannia to the Starrucca Railroad Viaduct. 25 miles out. I was wondering if it would be possible to hike up to the approach and ride my MTB across. The Viaduct is built out of Pennsylvannia Bluestone, built in 1847, is 1,200 to 1,400 feet across, and is 110 feet high with no guardrails. Top surface may possibly be covered with crushed stone. If there is crushed stone and it is slippery, I could just walk across pushing my MTB.

What happens if a train comes?

I guess they don't call you Rambo for nothing!

Is it an active railroad?

Yes, trains still roll over the Starrucca Viaduct.
