Description

The Steam Railroading Institute RBLX is a Roblox group inspired by the real-life nonprofit museum and heritage railroad. We focus on preserving the history, technology, and experience of American steam railroading. Our group features the legendary Pere Marquette 1225, the steam locomotive that inspired the Polar Express. Join us for excursions, restoration projects, railroading exhibits, and community activities, keeping the legacy of steam alive in Roblox! Note: We are a fan group and are not affiliated with the real Steam Railroading Institute.

Membership history

Growth

2 measurements spanning 3 days, net -1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 37–38 and does not start at zero.
