speed and cutoff

[nw-mailing-list at nwhs.org]

I do have something about cutoff percentages. You can send me your calculations after what I give you is sent, in case that changes anything.

Thank you,

Bud Jeffries

        That Would be great. Take your time. I can email you the spread sheet of the exhaust steam calculations and the Lempor exhaust Calculator.


        Thanks and Merry Christmas,

          John,

          I have some information about some of these classes. But I will need a few days to get to that and dig it out. This time of year is a little hectic, so bear with me.

          Best wishes,

          Bud

                  Group,

                  Another question may be someone will know or maybe not?

                  The class A developed max HP at 40mph, right? With a full tonage train at that speed what would be the average % of cutoff on the reverser?

                  The Y6b is at 25mph? % of cutoff?

                  S1a at 15mph? %?

                  The class J running a heavy train at say 70mph. what would the % of cutoff used?

                  I am working on determining the pounds per second of steam being exhausted by these engines. I was looking at the use of other types of front end arrangements (Lempor Exhaust) on these engines. These are the last variables I need to know.

                  Thanks,

                  PS. Louis Newton, Bud Jeffries, Ed King, or others, do you know?
