[quote]QUOTE: <i>Originally posted by malcolmyoung</i> <br /><br />On articulated locomotives, both simple and compound and including Garretts, both units always seemed to be perfectly syncronised. Should one engine unit go into a slip and get out of sync, it would always get back into sync within a few revolutions of the wheels after the slipping stopped. By syncronised, I mean four even exhaust beats for every revolution of the drivers. Why should this be? There was no mechanical connection between the two engine units. The only place where the two units were even remotely connected was in the blast pipe, and then not always as some locos had double blast pipes, one for each engine unit. I have never been able to find a satifactory explanation for this phenomenom, any Ideas??? <br />Malc. <br />[/quote] <br /> <br />Not true, Malcolm. Watch and listen to any video of N&W 1218 and you'll note the two engines get in and out of synch - the exhaust, especially climbing a grade, tells the story. <br /> <br />Timz - I think for purposes of this discussion, we're saying that "in synch" means when the two engines are exhausting simultaneously, whether their rod positions be identical, 90 degrees, 180 degrees or 270 degrees out of phase. <br /> <br />Old timer
