Thanks my dad plans to order an sound decoder for me

I was looking for information about an sound decoder for it and my dad has never installed one before

For an couple of months I will not be putting an sound decoder in it
My dad just got my Bachmann Railfan 4449 fixed on Friday

Are the holes little? and it is the 50201 I have
I plan next time to install an soundtraxx decoder on it,
tsunami heavy steam

I was not sure if it had any

I've been wondering if the railfan 4449 in ho scale has predrilled speaker holes or not because I looked at the bottom of the tender and I didn't see any

My dad does have long shank couplers and we had the problem on the 18" inch curves

no

The couplers on the cars are knuckle couplers but the couplers looked like thishttp://4.bp.blogspot.com/-8gfIofuBlKY/UtVPp4mWWbI/AAAAAAAAAMU/Vy0ofElSurI/s1600/MCH52.jpg

22 inches

My dad fixed the problem with the tender on the bachmann railfan 4449

cars are 72" inch

Original

When I connected the daylight cars to the 4449 the cars would come apart when the train goes around the curve

Yes
