ah ha!
interesting..thanks Scott.
yes, looks like the "original" Norfolk Southern (a totally different railroad than todays Class-1 Norfolk Southern)
did in fact have a few units without dynamic brakes!
but..they were GP38's...not GP38-2's..
so if USA trains used those units as a guide for their 1/29 scale models, they got the wrong engine.
(there are several external differences between a GP38 and a GP38-2)
Looks like the original NS had seven of these units:
www.rr-fallenflags.org/ns-s/ns-s.html
these seven units became Southern units when SOU absorbed this "first" NS.
lets see if we can track these down..im curious!
this page:
www.norfolksouthernhs.org/history.html
says Southern rebuilt them all with high-hoods!
ok..here we go:

yes, technically TODAYS NS had GP38's without dynamic brakes!
there were seven of them..
they had high-hoods.
and they werent even GP38-2's..they were GP38's..
so if USA trains picked those 7 oddball units (high-hood GP38's) as the deciding factor to make their
low-hood GP38-
DASH 2 the basis for offering them without dynamic brakes,
they picked the worst possible prototypes..
NS had seven high-hood GP38's without dynamic brakes.
as opposed to over 500 (by a rough count) actual GP38-2's
WITH dynamic brakes.
so still...not one actual NS GP38-2 without dynamic brakes..
USA trains screwed it up..no way around it.
their NS GP38-2 model should totally have dynamic brakes.
I hate to always bust on USA trains..but they make it too easy..
because I do actually think their models are excellent!
I am actually a big fan of their engines!
great detail, very nicely made..its just the paintschemes that are always messed up.
(and now a major detail like dynamic brakes too)
I should say that I
LOVE my Alco PA's! seriously..they are awesome!

and actually my favorite engines I own!
I even gave them their own webpage!
gold.mylargescale.com/scottychaos/LVRR_PA.html
but I cant buy their LV GP38-2..because the paintscheme is wrong in every possible detail..
and I mean EVERY detail..there is not one single thing that is correct..
if it werent for that, I would own a trio of them right now..
instead, I will have to someday buy two or three USA GP38-2's (any roadname)
strip the paint, and custom paint them myself in the LV scheme..
basically, from my perspective, they dont have a LV GP38-2...I will have to paint my own.
