Embodiments herein disclose an electric railroad retarder having a plurality of retarder modules. A retarder module comprises a gear cam assembly disposed between a first brake unit and a second brake unit. The gear cam assembly comprises a first position arm plate and a second position arm plate that are connected to a cam using a first positioning arm and a second positioning arm. The cam rotates to perform one of: compress a first brake spring, a second brake spring, a third brake spring and a fourth brake spring to hold wheels of a railcar; decompress the first brake spring, the second brake spring, the third brake spring and the fourth brake spring to release the wheels of the railcar; and separate the first position arm plate from a first spring base plate, and the second position arm plate from a second spring base plate to allow insertion of a shim.
