Source continuity: this live episode uses the Rio Piedras / Calle Ferrocarril source-lock, final caption/source packet, and platform schedule receipt listed below.

## Public Title

`Río Piedras: la calle del tren que todavía tiene recibo`

## Source-Safe Thesis

The receipt is not that the viewer's station/apartment/1855 claim was proven. The receipt is that Río Piedras was a transport hub and Casa Vigil at 1018 Calle Ferrocarril is a documented 1898 National Register building that keeps a physical receipt on that street.

## Receipt Spine

- EnciclopediaPR describes Río Piedras as a strategic passage between San Juan and the interior, with coaches, tram, and railroad service shaping its growth.
- Luis Pumarada O'Neill's railroad-history article supports the Ubarri route between San Juan and Río Piedras and the later trolley/rail context.
- The National Park Service / National Register documents Casa Vigil at 1018 Calle Ferrocarril, Río Piedras, with significant year 1898.
- Wikimedia Commons provides a supporting visual reference for Calle Ferrocarril 1018, described as a vernacular island-architecture example in Río Piedras Antiguo.

## Guardrails

- Treat the viewer comment as a lead, not proof.
- Do not claim Casa Vigil was the old train station.
- Do not claim the building has been apartments.
- Do not use 1855 as a verified fact.
- Do not imply the National Register source says Casa Vigil is railroad infrastructure.
