The M-1 RAIL streetcar project has set up an assembly line near Cass Avenue in Midtown Detroit to weld steel rail into about forty 560-foot-long “strings” of Continuously Welded Rail (CWR).
Using a track excavator, 80-foot pieces of rail are moved from the recently-delivered stock of steel onto an assembly line; some prep grinding is done by hand, then the rail is pulled through to a flash butt welder.  Flash butt welding is a resistance welding process that does not use filler metals to connect the rails; instead the welder melts both ends of the rail together by heating up to as high as 1600 degrees and then pressing the molten ends together forming a high quality bond. .  The welded section is then polished.  It takes between 10 and 15 minutes to complete one weld.
As many as seven construction workers participate in the welding operation; the M-1 RAIL crew is collaboration between Construction Manager Stacy & Witbeck, Inc., Detroit-based Farrow Group, Inc. and Crystal Lake Illinois-based Holland, LLC.
The 560-foot-long strings of continuously welded rail will eventually be moved onto Woodward Avenue in preparation for track installation.
