Tatra T7B5 is a four-axle, high-floor electric tram manufactured by ČKD Tatra in Czechoslovakia between 1988 and 1993. It was developed as a modernized successor to the T6 series, although only a small number were produced. Due to its limited production and scarce documentation, the T7B5 is considered one of the least-known Tatra tram models.
Overview
The T7B5 was intended to introduce updated electrical equipment, improved passenger comfort, and a more modern exterior while retaining the proven mechanical platform of earlier Tatra trams. Most units were delivered for testing or limited operation rather than large-scale fleet deployment.
Design
Although designed as a successor to the T6B5, the T7B5 shares a very similar overall appearance with the earlier model. The body profile, window arrangement, and general layout closely resemble the T6, making the two models difficult to distinguish at a distance.
Exterior
The most visible difference between the T7B5 and the T6B5 is the design of the passenger doors.
- The T7B5 features **doors with windows only in the upper section**, giving the lower panels a solid, unglazed appearance.
- The T6B5 typically uses **full-height glazed doors**.
Other minor exterior differences include slightly revised front-end styling, updated lighting, and small changes to roof equipment.
Interior
The tram features a high-floor interior with wide aisles, seating for around 30 passengers, and a total capacity of approximately 160. Heating and ventilation systems were improved compared to earlier Tatra models.
Electrical and mechanical systems
The T7B5 is powered by four TE 023 traction motors and uses standard Tatra bogies with resilient wheels. Braking is provided through a combination of electrodynamic and pneumatic systems.
