Marysville, PA
Public viewing from the Marysville riverfront (west bank) or along PA-441 / Rockville Rd on the east bank. The bridge itself — the world's longest stone-masonry arch railroad bridge (3,820 ft, 48 arches) — is active NS Harrisburg Line, completed 1902.
View from public roads and riverfront only. The bridge is active NS mainline; trespassing onto the structure is prosecuted and physically dangerous (no walkway, train clearance is tight). River swimming/wading where viewing is fine in summer where allowed by signs.
Roadside parking along River Road in Marysville on the west bank. East-bank views from pullouts along PA-441; do NOT park on private property.
Morning for westbound trains (sun on the east face); late afternoon for eastbound. The bridge runs roughly E-W across the Susquehanna.
High — NS Harrisburg Line and Buffalo Line both use the bridge. 30-50 trains/day plus Amtrak Pennsylvanian once each way. The bridge is also visible to Amtrak Keystone passengers headed onto the Pittsburgh Line via Enola.
Marysville has a small downtown with cafes. Full services in Harrisburg (~5 miles south across the river).
For the parent, spouse, or friend along for the ride — restrooms, food, and what to do while your railfan watches trains.
Enjoy a scenic spot while your railfan watches trains cross the historic Rockville Bridge.
While your railfan is busy, you can take a leisurely stroll along the riverfront or explore the small downtown area of Marysville, which has some charming cafes. If you're up for it, there’s also a nearby playground where kids can burn off some energy.
Safety: Make sure to keep your kid at least 25 feet back from any tracks and only view from designated public areas.

A 70-200 or 100-400 at full reach gets shaky after a few minutes of waiting. Carbon-fiber monopod folds to ~16in and weighs nothing. Worth its price the first time you nail a 1/250s shot of a stopped train. ($40-$80)

The no-setup railfan scanner. Comes pre-loaded with AAR railroad band channels — hear road comms, dispatchers, defect-detector calls. Knowing a train is 20 minutes out beats staring at the horizon. ($110-$130)
