The 185 Series was developed by the Japanese National Railways (JNR) to replace its fleet of 153 Series express trains and also work as a regular train if necessary. 

However, it was later decided that it would also be run as a limited express. Having a certain type of train run as both a regular train and limited express was a first for the JNR.

Due to this design, the 185 Series has better acceleration but a lower top speed than other limited express type trains.

As a limited express, its interior was somewhat lacking and as a commuter train, a little tight. This made it a somewhat unpopular train among riders.

The 185 Series has since been improved and continues to be operated as a limited express by JR East.
