I noticed (jn the 2016 catalog) that Bachmann has addressed many different historical periods in history. there are Older steam engine with what I assume are appropriate rolling stock, the following generations of steam, the "Prairie, Mikados, Challengers, Big Boys etc. all with time period appropriate rolling stock.
I was hoping to find appropriate rolling stock for my Milwaukee, Chicago & Puget Sound (later changer to Chicago, Milwaukee & Pacific) Rail Road. The MC & PS operated in the first 12 years or so of the 20th century. I would also like to have cars and engines appropriate to the years after it became the Chicago, Milwaukee & Pacific.
  Now I figure the rolling stock such as box cars, refrigerater cars and cabooses were on frames of steel and the super structures were made of wood. Tank cars and grain, coal, as such....I don't know for sure but I assume they were steel.
Having said all that...
Does Bachmann have rolling stock identifiable as being correct for my road in my periods in history? Is there a reason I do not see periods of use listed with the cars in the catalogs?
I have researched the internet and found some great sites (http://www.craigmagnuson.com/laconia1.htm) and (https://www.mrha.com) and will more closely check them out, in the mean time can anyone give me some pictures or examples of the rolling stock I need?
Yes, I am new to the hobby!
Thanks!

 I'm new to the hobby. My wife gave me a ready made layout built by an older gentleman that just got too old to do much any more.
It's 16 Feet X 2 FEET; has several tunnels, 2 river crossings, 2 banks of control switches (1) to actuate the 9 turn outs and 1 criss-cross; and (2) Many 3 position switches to control a section(s) of track, either "FWD", "REV", or "OFF". The switches are laid out on a pull out drawer that has a rough map of the line(s) and the switches in the approx. position of the section of the line (track) they control. The turn-out bank is 6 or 8 switches that control most of the turn-outs but I think 1 or 2 have wiring issues as nothing happens when I throw that switch.
I have lots of rolling stock, some from European suppliers and a lot from Bachmann.
I have a Bachmann 4~8~4 Southern Pacific 4405 Great Northern Steam loco (P|N 58001) with a Tender, (P\N58101). I also have 2 modern Bachmann diesels as EMD SD 45 and a N SW9/1200 LOCO N&W #3375 This one is 3/4 the length of the SD45.
The PO used the power supplies (17VDC) that came with the train sets, cheapie types; there are 2 to control different sections of track. I bought a dual set up from MRC, it seems to have a lower output than the original power packs do as the train doesn't go as fast or perform well at those really slow speeds and some times after the loco has stopped it won't start (even when applying full power)unless you give it a nudge (push) and then it screams off down the line! Not very realistic.
So just what is the DC operating voltage and required amps to run the Bachmann motors? Are the motors of less quality than other MFRs use thus requiring higher start amperes? Is my new power pack/throttle too weak? The power pack specs are as follows: MRC 1278 Tech 7 AMPAC 780 Dual Action Train Control. 14.5 VDC, EACH THROTTLE @10VA, 14.8 VAC. I know the AC is for accessories.
I sure hope to get a response soon! Thanks for reading my post!
