The tail end of the Beer Line featured The Pabst Brewery, Blatz Brewery, and Schlitz Brewery, as represented here (courtesy of Model Railroader magazine); the black and white photo is the real Schlitz Brewery (also courtesy of Model Railroader):
While the actual Milwaukee Road Beer Line and the engines that ran along its tracks may be a thing of the past, authentic British beer engines in Milwaukee are a thing of the future! Actually, they're available now:
Our authentic British beer engine is manufactured by Harry Masons and was featured in BTV episode 27 Ale Lang Syne. This unit is a 1/4 pint pull with a cooling jacket and is designed to clamp on to a bar surface for easy installation. Comes with plastic nut, tail piece, compression washer, and drip tray. Needed to serve from a cask but not included are: a cask tap, plastic nut, plastic tail, sealing washer, and 1/2" tubing. Optional sparkler is not included. The cooling jacket can be used by running cool water through the jacket with 3/8" tubing.
