s. 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.
