Description

Welcome to the PRR Duplex trust! This group was originally a joke, seeming that the Duplex might never beat Mallard's records. However, it became a successful Ro-Scale group. We hope you play our group Ro-Scale game. However, the game is not YET free-drive. Once complete (or during testing days), free-drive will be enabled. In the mean time, make yourself comfortable, and thanks for visiting us!

Membership history

Growth

2 measurements spanning 25 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 109–110 and does not start at zero.
