Early GEs had 16 notch throttles, but they worked in MU by having an extra pin, sort of an odd-even.  Notch 1 and 2 would activate notch 1 on 8-notch throttles, 3 and 4 would activate notch 2 and so on.

Zug:  Takes a couple of tries, but I have it now.

Were there ever "notches" on locomotives?

 

Modern engines have notches for power.  They go click-click-click. Unless it's an old desktop, then it's like clickclickclickclickclick...."damnit...I wanted ONE notch, not 7!"  (some of those controllers are a bit worn)

Dynamics have no notches.  It's smooth the whole way.

 

It's been fun.  But it isn't much fun anymore.   Signing off for now.

Most roads frowned on Engineers carving notches in the handles for every cow they struck.

Our SW1 (ca 1939) has no notches - it's more like the rheostat on a model train transformer.

Our ALCO's have no notches on the dynamics.

No half notches in power. In dynamics, no actual notches. Just dynamic positions of Set Up and position 1 thru 8.

Not so fast.  Not that this applies to modern road power, but there were GEs that had half-notches.  Will  Davis probably has technical material on them... if I recall correctly the eight notches controlled the engine speed (probably doing as EMD did to avoid critical speeds in the engine) and the intermediate notches bumped up the generator field excitation.  This of course needed an additional wire in the MU cable.  At least some U-boats used the 16 notches for dynamic.

Thank you for the info!  I almost short-circuited this by putting your name in the heading, but wasn't sure if you were working or might miss it.  

We were watching a crew change this morning and they sat for about 20 min before the train showed up, which got me to thinking..... again...

Only because I don't know the answers:  notch 8 - is there 1/2 a notch for any of the numbers?

Crew cab drops off and picks up a crew from a train.  When does the time start for the crew waiting for the train and when does it stop for the departing crew?  

 

No half notches in power.  In dynamics, no actual notches.  Just dynamic positions of Set Up and position 1 thru 8.

Crew time starts when you go on duty and ends when you tie up.  Since you can only perform service for 12 hours, the time it takes to get to the train counts toward the 12 hours.  If it takes 2 hours to reach a train (or for the train to show up at a terminal) you can only work an additional 10 hours after climbing aboard.  After 12 hours you can't work, but are still on the clock until you actually tie up at a terminal.  Over 12 hours on duty and the required off period gets extended by the time over 12 hours.
