[Snapper]

Friends of Northern Pacific, hello.

I seek websites which speak about passenger trains composition.

On my layout, Northern Pacific between 1960 and 1970, I wish to make circulate this type of car :

But when is it really? composition, motive power, etc…

Thank you in advance for all the infos which you will be able to bring to me.

So are we talking a summer train?
A winter train?
A local train?
1st or 2nd class train?
A jointly operated train?

These kind of trains rate how many locomotives, kinds of head end cars, how many coaches,sleepers (if any),diners and domes.

A jointly operated train can have cars from both railroads i.e SP&S trains from Portland to Spokane had NP and GN cars some sublettered SP&S or though cars from connecting railroads (sleepers)
