Except.  Why the rear most derailed cars turned outward?  Maybe this was the rear of the train and the derailed locomotives were pushers.

That is one really sharp curve for the prototype, looks like on a layout almost.  What are all those horizontal things on the ground that look like another track? Welded rail laying on the ground?

Carts?  Like in a grocery store?

😂😂😂😂😂

If you told us which model you have, we could help you.  Bachmann makes several 4-6-0's in several scales.

The missing pieces are called crosshead guides.

Make new ones out of styrene stock to match the ones still on the other side.

I received a nicely custom decaled older Bachmann consolidation along with a bunch of other stuff I bought last year. The mechanism had been taken apart and we assembled badly and could not be repaired to operating condition.

 I just put the boiler shell on a new Bachmann mechanism and the tender shell on a new tender floor with a sound decoder.

I also have around 50 locomotives. But I basically started Model Railroading in the year 2007 after being out for 41 years.  Everything I had from 41 years before was destroyed in a fire a few years before.  So I basically started over in the DCC era. I have three DC locomotives, but they are all on hold waiting for decoders.

Presently, I don't run diesel locomotives, i'm modeling the 1930s, but I have around 15 I bought over time to run at some future time on another layout. The reality of model railroading today is that nothing is available very long, nearly everything is limited run in comparison to the days of yore.  It's a good thing I bought those diesels because none of them are available anymore.

Great.  Thank you!

Plastic or die cast?

The KCS Southern Belle inspired paint scheme is beautiful and about to be lost, so much better than solid red.  Count it among the other lost ones like the warbonnet and the black widow.

If the view is looking west and slightly north, with downtown in the distance, this is probably the old T&NO (SP) crossing the old I-GN (MP).  I crossed those diamonds many a time on SP No. 2 and No. 5.  That was 60 years ago more, so nothing looks familiar anymore.

I wish that CPKC Would acquire L&A Ten wheeler number 503 that's rusting away in Port Arthur, Texas.

Putting the iron through a plastic shell was basically a joke.

But. Fill me in.  I've not been very aware of availability of separate DCC only Decoders without sound, and a separate sound only decoder. If that's the case, can one piggyback a sound only decoder onto an existing Silent DCC Decoder.  Please elaborate on this for my enlightenment.

Getting professional installation of DCC is one of the best ways you can spend your money, in my thinking.  Unless you really, really like playing with electronics and extreme micro soldering.  Some folks do, more power to them.  But we have gotten people on here before whose first question is how to make the train go and the next question is how do I install DCC.  I've spent a fair amount of money having a pro install DCC/sound in well over 25 engines, but then, he is a friend and gives me good rates.  Because of that, I've never burned out a decoder or put my soldering iron through a plastic engine shell.

It's easy if you let a pro do it

Yeh.  EZ Command is just the thing in certain settings.
