[SEL] Junkers 2HK65 (now loco engines)

[Jim Kirkes]

Hi Elden,

No, I don't think you have been all wrong.  Some railroads 
have favored GE and some EMD.  The big 6 buy a lot of both 
with Union Pacific ordering 1000 4000 HP diesels from EMD. 
In spite of that GE out sells EMD by a wide margin. EMD 
still makes two cycle diesels and they do meet current 
emision standards. The two cycle engines have some 
advantages in that they load faster.  Ttheir big draw back 
is that they are 16 cyl engines and the GE engines are 12 
cylinder so the 16 cyl overhaul cost is considerably more. 
Maybe not a big deal for one engine but if you have a couple 
of thousand it stacks up fast.  Fuel economy has been a big 
issue for a long time and EMD has managed to stay in there 
with the two cycle design.

BTW the latest development in loco design is the "gen set" 
loco which are becoming popular for yard use.  The loco has 
3 or 4 700 HP diesels,  they come on and off as the load 
changes and stop completely if not used for 10 minutes or 
so.  The fuel saving is claimed to be 60% over a one diesel 
loco.
This big saving comes because most diesels in yard service 
do not operate at full power much of the time.  At full 
power for long hauls the single engine is the better 
arrangement.

Jim:

Now, THAT's interesting!  A number of years ago, I toured 
the CSX overhaul facility in Louisville, KY (before they 
moved it somewhere else).  I believe the engines were V-16 
G.M. Electromotives.  I also thought they were two cycle 
because GM was big in 2-cycle truck, bus, boat and heavy 
equipment engines.

Have I been wrong all this time?

Take care - Elden
