How do Bulleids Work?

Post by 35005CP on Sun Aug 23, 2009 6:53 am

Hi all,

Following a Round Robin email regarding Tangmere's beat not sounding right - I thought I would start this thread; in the hope of starting some good dicussion?

How many beats and reliability??? Free for all to discuss! Carry on!!!

Somewhere on a videotape at home the narrator at the very end of the programme comments that 35028 Clan Line has an uneven exhaust beat as well. It's an old programme called "Express Locomotives of the Southern Railway" I think.

Having seen Tangmere on the mainline in various locations over the past 18 months I can't say I've noticed anything odd about the exhaust beat, or has it been sorted?

Three cylinder locos won't have a perfect beat, even when perfectly set up. The exhaust passages are of different length and shape. The inside cylinder of Bulleids is 8 degress above the horizontal but the crank is offset too, so this may not be a factor on the audible beat.

Is that because the inclination of the inside cylinder causes the angles on the crank to be uneven? 120° +120°-y +120°+y (y= the angle of inclination of the inside cylinder)?
