The invention provides an overload detector with a simplified system configuration to be applied to a railway car having a connecting bogie. A connecting bogie 52 (two axle bogie) having front and rear wheels 52 C and 52 D are disposed to extend between a first car C<SUB>1 </SUB>and a second car C<SUB>2</SUB>. The front and rear cars C<SUB>1 </SUB>and C<SUB>2 </SUB>are supported via air springs 52 A and 52 B on the connecting bogie 52 . The other end of the car C<SUB>1 </SUB>is supported via air springs 51 A and 51 B on a bogie 51 (two axle bogie) having front and rear wheels 51 C and 51 D. The other end of the car C<SUB>2 </SUB>is supported via air springs 53 A and 53 B on a bogie 53 (two axle bogie) having front and rear wheels 53 C and 53 D. Pneumoelectric converters 41 and 42 are disposed along paths of pneumatic pipings 21 and 22 , and the inner pressure of air springs 51 A and 51 B is converted into an inner pressure signal AS 1 , and the inner pressure P<SUB>AS2 </SUB>of the air springs 52 A and 52 B is converted into an inner pressure signal AS 2 . The inner pressure signals AS 1 and AS 2 output from the pneumoelectric converters 41 and 42 are input to a computing processor 3 . Overload is determined based on signals AS 1 and AS 2.
