81-71M is a refurbished version of Metrovagonmash 81-717/81-714 metro rolling stock. It is used on the Prague Metro. Similar modernizations (81-717M/81-714M) are used on the metro systems of Tbilisi, Yerevan and Baku.

A nearly identical set was delivered to Kyiv Metro as part of the Slavutich project, numbered 81-553.1 (12Mt), 81-554.1 (13Mt) and 81-555.1 (14Mt).

A train consists of five cars, two end carriages (2Mt), two trailer cars (3Mt), and one intermediate driving car (4Mt) in the middle.

Development

When it became clear in the 1990s that the old soviet metro trains of the series 81-717.1/714.1 and Ečs wouldn't need an overhaul but a full rebuild to further operate savely, Škoda Transportation developed a prototype of a fully modernised 81-71 train which was presented to the public and went into service in 1996. In the following years, nearly the full fleet of old 81-71 trains was refurbished, except a five-car set, which is preserved at Zličín (B) depot for special occasions, and one 81-717.1 carriage, which is stored in the MHD museum Stresovice.

Operation

Currently, there are 93 sets of 81-717M/714M operating in Prague metro, of which 41 are running on line A and 52 on line B^[1]^[2].

81-717M/714M

Thought looking similar, there are technical differences between the 81-71M and the 81-717M/714M.

Tbilisi

In the mid-2000s, Tbilisi Metro started modernizing its Ezh3/Em508T and 81-717/714 type trains based on the 81-71M, also under usage of the same front part.

Baku

Yerevan

81-553.1/554.1/555.1 "Slavutich"

In cooperation with his Russian partner ZAO Wagonmash, Škoda Transportation produced a new underground train for Kyiv metro based on the 81-71 series, where Škoda Transportation took part in supplying traction and pneumatic equipment.^[3] Škoda also produced the fiberglass front parts for the 12Mt end cars which were also used for the 81-71M trains.
