Class 207M is a prototype series of Polish light Diesel Multiple Units (aka railcars). Only six were made in following configurations: * two cars - a set of ''207M'' power car and ''207Mr'' trailer-control car (PKP designation SA101+SA121) * three cars - a set of: ''207Ma'' power car, ''207Mra'' trailer car, ''207Mb'' power car (PKP designation SA102+SA111+SA102) == History == By the end of the 1970s, steam traction in Poland was mostly retired. Non-electrified lines became operated with diesel locomotives. For short distance passenger traffic (mainly suburban trains) PKP was seeking a more economical solution than a heavy diesel locomotive pulling few cars. The obvious solution was the use of railcars. However, due to politics-related economical problems Poland was facing in 1980s, it wasn't until 1990 that the first cars were produced. The class 207M was developed in ZNTK Poznań by a team led by Polish renowned rail transport engineer Ryszard Suwalski. The concept prospected trains from one up to four cars in consist. Only 2- and 3-car versions were made, three of each. Again, due to economical difficulties class 207M never went into serious production. After 2001 a larger contingent of railcars/DMUs went into production and they were based on newer projects than 207M. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Class 207M」の詳細全文を読む スポンサード リンク
