An adjective used to describe certain rail enthusiasts that think every old EMU / DMU / Diesel Locomotive / Electric Locomotive are better then any and ever new train that is built They also climax at the any sort of thrash or horn they get.
You can spot a foamer by what they were or what they carry
they usually have an iPad and a tripod or some shitty camera and are aged between 16 - 150 years old
Person 1: The Class 319 is a good train and the Class 700 is a crap train
Person 2: God you are such a foamer, the Class 319s are awful.
