Landerbahn coaches

The next Länderbahn coaches were built by the DRG after 1920:

• B4ü-pr20a
• C4ü-pr13
• C4ü-pr21
• C4ü-pr21a
• C4ü-pr21b
• C4ü-pr21c
• Pw4ü-pr12
• Pw4ü-pr16
• Pw4ü-bay23
• C4ü-bay23
• AB4ü-sa23
• C4ü-sa18

These Länderbahn coaches were built in expectation of the first standard design coaches. Because there was a shortage of express train coaches at the beginning of the thirties, the DRG decided to built a number of Länderbahn coaches.
