The most boring passenger coaches .... in my opinion
Builder: ZAKLADY PRZEMYSLU METALOWEGO H.CEGIELSKI - POZNAN PRZEDSIEBIORSTWO PANSTWOWE, type 216A. Built in 1967 - 1968.

51 73 20-80 201 - 234, Bm.

51 73 39-80 051 - 066, ABm.

51 73 59-80 001 - 012, Bcm. Some of them were demoted to 51 73 59-10 0XX-X
Plans for rebuilding 9 of them by HELLENIC SHIPYARDS were made but not continued. These 9 coaches are still '' waiting '' half - rebuilt at HELLENIC SHIPYARDS' area. They would get the numberings 61 73 20-67 241 - 243 (i think '' Bmy '' , ex- Bm) and 61 73 19-76 201 - 206 (i think '' ABmy '', ex- ABm).
