ok so im sure you guy hate the rapidos that bmann used to supply, and possibly the dummy couplers that they now supply on their new cars,
( i know i do)

so my quick fix is simple, possibly inexpensive.
i first order a few 8 packs of Kato Unimate Short Shank Couplers ($4 for 8 )

then when i get them, about a week, i put the unimate couplers together (3 pieces) and file down the lips at the ends of the coupler, and i set them aside, i take off the coupler box of the truck/s, be careful those springs are jumpy, and they are hard to find if they fly out, and i remove the coupler from said coupler box, toss set aside or w/e with those, and replace the couplers with the Unimates ( the unimates are for pilot mount, but with a file that can be modified for Bmann Coupler boxes).
i am very careful to replace the boxes b/c the coupler shaft is a tad thinner when the lips are removed so they slide back and forth easily, and basically that is a quick fix for those couplers, the cars look a lil closer together now, and the Unimate couplers will still operate (almost perfectly)

i hope this helps! also here is a basic diagram for the Unimates using the keys on my key board....

this is what the end of the Unimate couplers look like before:  -[
after you file them they should look like :   -|     

I need parts for my dash 8,
How much will a new frame/motor/trucks/gears etc
cost me?

i have an older Dash 8-40C that is needing parts replacement.

i need two trucks i motor and possibly a new light board, does anyone know how much this might cost? or should i buy a new one?
when i got her, she ran like a angel and i would like to get that back to normal.....

Please Help and thanks for your time

Two P42 to pull 4 amfleet cars? thats a load of malarky!! it takes my ONLY p42 to pull 5 Amfleet coaches

like i said file out the pick up tabs....or you cand send them my way and ill do it for free.. i have too much time on my hands....lol 

Herc Driver also try to widen the pick up tabs holes too they cause the most friction in my trucks, that is untill i filed them too!

try repainting the loco man, but i forgot about Kato i think they have two versions out, maybe.

LL (Walthers) still has a F40ph out and they pull like a semi! as for the E60's you have to buy "The Centennial" set it comes with 3 Amfleet coaches and its a good runner.

they roll better if you file the hole bigger on the trucks, the most friction is on the pick up tabs, those need to be filed too

i was for the last few hours before , like the real loco, it poured out smoke out of itself!    eh oh well!

it was meant as a joke um i was running it at 35 smph, but i guess i ran it way too long, um like 22 hours....    

well i need a replacement motor, I guess 14 volts is way too much power 
stupid DCC....lol

sorry.
but you could repaint the units
to a diff RR

Mike you beat me to it!
And the UP didnt have any Hi hood GP50's

ok but i will tell you this. after using some lube it is now 20% quieter even at high speeds!!
At 35 smph you cant hear much a lil bit of groaning but not much, that and i ran her all night long and so she is a good runner

People you have to get one of these!
i got one today and it runs so beautifuly for a standard line i am not even joking!!, a bit noisey but a bit of lube in the motor will shut her up!!!

It maybe a UP ( UP never owned any but i dont care!! ) but it runs awesomely!!
