Sydney prison tram from 1909, Australia

This was a heavily secured electric tramcar which holds the status as arguably the world's only purpose-built prison tram from the ground up. 

Built at the Randwick Tramway Workshops in 1909, it was explicitly used by the New South Wales Police Department to transfer inmates between the Long Bay Penal Institution (Gaol) and the Darlinghurst Court House. It ran four times a day for forty years.

To keep inmates away from the public gaze, the 15-tonne tram featured a steel floor, thick drab walls, a side corridor, and six heavily secured, windowless cell compartments (four for men, two for women) capable of holding 48 prisoners total. It proudly displayed a "No Passengers" sign on the front and rear windows because prisoners were not legally classified as paying passengers. 

Despite its imposing, escape-proof reputation, it became notorious on March 4, 1946. While the tram was traveling through Kensington, a famous Sydney criminal named Darcy Dugan (along with an accomplice) used a serrated bread knife stolen from the prison kitchen to cut a hole straight through the tram's thin, canvas-covered wooden roof, climbing out while the tram was in motion. 

The tram was withdrawn from service in early 1950 when the police department transitioned to road transport. Today, the fully restored, real-world Prison Tram 948 is on permanent display at the Sydney Tramway Museum in Loftus, South Sydney, where visitors can still see the patch on the roof from Dugan's legendary escape.

cars in Bermidji, Minnesota, early 1950s

The dark-colored car parked on the far left in front of the Rex Café looks like a 1951 or 1952 Kaiser Deluxe (or Manhattan) sedan. It is identifiable by its distinctive "widow's peak" dip at the top center of the windshield, unique grille profile, and rounded body lines characteristic of Kaiser-Frazer styling from that specific era.

2-8-0 'Consolidation' type steam locomotive at the highest point on Peru's railway, circa 1910

Built by the Rogers Locomotive Works. The railway pass today is operated by the private concessionaire Ferrocarril Central Andino (FCCA). While the open-air tracks right at Ticlio station are mostly bypassed by modern traffic via the nearby Galera Summit Tunnel (which pierces the mountain ridge at an altitude of 15,692 feet / 4,783 meters), the trans-Andean mainline itself remains fully operational.
