Diesel locos

Atlas analog diesel

I have purchased an Atlas HO Master GP-40 - Analog engine and want to install a sound decoder.  My problem is I cannot fine the exact light board anywhere on the Atlas site.  It has a 21 pin as well as an 8 pin socket.  If I go with the 21 pin how is the speaker installed?  The existing board space is too short for any board replacement.  I do believe there is a socket on the existing board that may be a socket for a speaker plug.  Since I cannot find a detailed drawing of this light board where do I go to find one.

Sorry to soil the day of any strictly realistic modelers, who might feel this doesn’t belong here, but I just finished work on a fun project, and I thought this might be a fun place to share it.

GP non-turbo exhaust stack

I'm modifying a Kato GP35 as if it were de-turboed and upgraded to a 16 cylinder 645C.  I've already modified the roof to remove the turbo stack and insert an air filter I cannibalized from an Atlas GP38-2.

Now I need to add the non-turbo exhaust stacks to the roof.  My "go-to" part would be the Detail Associates #2402.  Apparently, no one on the planet, including EBay, has any.

Any ideas who may have them?  Or, feeling like the more likely possibility, does anyone have an idea for an alternate, high-quality part?

Boxcab Diesel Track Cleaner

Or should I say "Boxcab Oil-Electric" (as folks didn't want to say "diesel" after WWI, for silly reasons)

I finbally got one... just ordered it today. I've been keeping quiet about it, because it's been in my watch list for over a week on eBay... I handed a flatmate some money to put into my PayPal, and he sent an e-check, which took a freekning WEEK to clear, but it clared this afternoon, and I managed to get it just as someone else put it in their watch list.

So anyway... here's the beauty right here:

Kato SD40 numberboards

I have a Kato SD40, new in box, that has been hiding in the closet since 2003. It is an undecorated model and, unfortunately, came without numberboard inserts. Kato USA does not have any in stock. Any ideas would be appreciated.

Modifying a chassis

I am kitbashing a Union Railroad "Buffalo" locomotive and, like the real life hyprid, the locomotive needs a long front EMD hood sitting on a Baldwin DRS 6-6-1500 Chassis.  The Bowser model of the latter will give me the chassis and trucks, etc.

First Locomotive - DCC and Sound - Questions

Hi all,

It's time to buy that first locomotive.

I'd like to get one with DCC and sound built in.

To get the sound to work, do I have to install speakers anywhere in the locomotive, or are they usually already there?

Also, what about sound in rolling stock?  Is this common?  I'd like to pursue this as well.

Thanks,

JR

The front on BN SD7's

Just bought a Atlas BN SD7.  Did they operate them short hood or long hood forward? I know Great Northern SD7's were operated long hood forward.
