The RT8D5 is a light rail vehicle built by Czech manufacturer, ČKD Tatra. The vehicles were manufactured for the Manila Metro Rail Transit System and were the last made by ČKD Tatra before it was taken over by Siemens.

After its traditional markets declined during the 1990s, ČKD had to look for new sale opportunities. One potential customer was Manila, which wanted to build a new rapid transit line, the present-day MRT 3. In March 1996 the first three-car tram was tested in Prague under the number 0029. It was a development of the KT8D5, retaining its control, proportions, and the front and rear sections and, unlike the later production vehicles, designed for bidirectional operation. It remained in Prague, was used in October 1998 together with the Tatra-T5A5 prototype, no. 0013 and the T3 no. 6663 for various crash tests in the main workshop in Praha-Hostivař before being eventually scrapped.

Typical RT8D5M three-car unit of the MRT-3, one of Manila's three rapid transit lines.

The first train was flown into Manila in 1997; the remainder were transported by sea. The vehicles are mainly operated in threes.

Each rail car is provided with five double leaf, electronically-operated, plug-sliding doors. The three center doors have an open width of 1,255 millimeters while the two end doors, 861 mm. Each train can seat 80 passengers and carry, under rush loading conditions, 394 commuters at any one time. The rail vehicles are articulated, eight-axle, three-section cars, designed for single-ended operations. The trains run at a maximum speed of 65 kilometers per hour. They run over standard rail tracks.
