I wouldn't call it "loyalty", but I'm partial to CNW and ATSF. There are some exceptions, though, as I have some UP equipment -- mostly heritage units.
Yes: N&W, NS, RF&P, Virginian, and ACL 
Ten years ago I ran Northern Pacific, Southern Pacific, Canadian Pacific and of course Santa Fe. These days it is 85% Santa Fe and 15% Western Pacific.
However, because I belong to a club I get to see at least 30-35 different railroads. We have everything from Amtrak to Ferromex. Good times. 
No......5 interconnected ones: NEw York Central, New Haven, Penn Central, Conrail mad NYO&W.

Nope. Even my freelanced line has to interchange with other railroads. In this case the UP and BNSF. Also half of my freelancer roster is still second hand units with patch jobs to add realism. Keeps things colorful
Mainly NKP, N&W, and C&O. But I have NYC, Southern and UP. I am trying to thin out though. With Rolling stock anything goes.
I think so?
I mainly model Union Pacific and have a strong secondary interest in Southern Pacific, with Weyerhaeuser Timber Co. logging thrown into the mix. Like Cappilot, my chosen roads are large enough that they don't limit spending as much as I would like, too many interesting locomotives.
As to rolling stock, it is a wide range of roadnames, as that is what the real trains hauled, especially in the transition era, which is my main focus, not too many all one road name trains, back then with the exception of coal hoppers and reefers and passenger, most trains had interchange traffic from all over the country.
I have a Nephew and a Great Nephew modeling the UP, with a Nephew modeling the Santa Fe, and another modeling NYC, so I have a few locomotives from those roads for when they visit.

I want all the trains on the shelves in the background please. I'll let you keep the others.
Thanks

Now you've gone and done it Peter... forgot about the New Haven, but only in the McGinnis livery. And I've got to make it over to Steamtown to see if they have the NYO&W 44 Tonner on display before it begins restoration. But I still DO NOT have a problem!!!
I have NYC & Christmas engines . I hope to add Pennsy and New Haven engines by June . I have been adding various different RR freight cars since 2015.
No, if the design or paint scheme catches my eye (and I can afford it), it doesn't matter what railway it is it has a place on my layout.
90% Western Maryland, 5% B&O & 5% PRR, plus an extensive collection of almost mint PW Lionel.
My engines and passenger cars are Long Island only, as I model a branch line. In regard to freight cars, I have a plausible variety from all over. I try to reflect what would have run on the prototype. I have a healthy motive roster, and have several Long Island engines from different eras.
I love the Milwaukee Road, like the BN, and have a full Atlas Zephyr set. That is why my 2 Rail railroad is called the ND&W, the Nebraska, Dakota and Western RR. Couldn't decide so I made my own. I suppose it goes back to I guy I knew that was not only a rivet counter but insisted on measuring the darned rivets. I created one so no one could tell me I was wrong.

No, by definition my railroad consists of parts of six different real railroads. Lots of joint trackage and trackage rights, just like in the real world. Add to that, pool power, and almost anything modern goes.
As above, my road is free lance, but interchanges with the Grande/ATSF "joint line", so Grande is the most important, with Great Western, Q, RI, MP, C&S, secondary, and UP and ATSF cars, no locos, found , as well as other "interesting" road freight cars. Locos, steam, are relettered for free lance, or Great Western , one steamer is for Grande, others would be for secondaries, steam, if found. There are gas electrics from some of the secondaries. Much is kit bashed. Sticking close to this saves money, but it is because little commercial is offered. the

Matt, there are about 200 pre and post WWII sets on those walls. Mostly Lionel, except for eleven fantasy sets (Lionel never made them so I made them myself). NOTE: I store a lot of extra cars in the sets so they look longer. Some pictures attached.
I would like to get rid of them so I can display my modern stuff now hidden under the train tables. It seems there is no way to sell them in China and shipping makes them hard to sell to the U.S. Let me know your arrival date. 
OK, that question could be a trap. If you run ATSF, does GC&SF count as Santa Fe? Does T&NO count as SP? T&P as MoPac? Or all of those lines as part of the SOU? LA&SL as UP? C&S as part of the Q? Ft. Worth and Denver as part of the C&S, being part of the Q?
I only run Penn Central. There are several locomotives decorated in predecessor road names, but they are all PC property. I run rolling stock from foreign roads that would typically be seen on PC trains. I make sure that all rolling stock is era appropriate. (No enclosed auto rack or intermodal here)
It does help keep cost in check. It also keeps the creative juices flowing as I have to kitbash or build quite a few pieces.
Tom
I like S.P. for Locomotives and Cabooses, Every thing else is what might run on the S.P. I remember seeing freight cars from all over on the S.P. and I try to follow that on my layout.

"Original" sets are great to have. But you know, I'm not a purist that way either. I pick engines I like and put what I feel looks good behind them. That's an impressive wall there. Definitely my style, looks great.
I run any railroad line that has connected to or through Chicago and Lionel Lines. I have a C&O engine and New York Central and Santa Fe. What do you know? They all connected to Chicago. Is there a railroad that hasn't connected to Chicago, even through a merger? If so, I may need to give trackage rights. It's my railroad.

In today's world, the only one of the big seven not going into Chicago is KCS.

I like the Kansas City Southern colors, so someday I may need to grant them trackage rights or 'lease' one of their engines.

PRR and ATSF. Born and raised on Long Island so I would love to add some local equipment. The old # 39 comes to mind.
Lionel Lines is always in the mix too 
I'm not a hi-railer, so I don't focus on any roadname in particular. I have always purchased items I thought were nice to look at. On my layout, you'll see the N&W Powhatan Arrow set passing a a CP set from 1980 only because I think they both look nice:
All of these may run past a 1991 Scale Hudson pulling a string of RailChief cars and a mixed postwar freight set headed by a Virginian FM.
My only rules are that a train needs to 1) mean something to me personally (e.g., a special gift from someone) or 2) look nice. I've never had a guest say, "Phooey! I'm outta here. Everyone KNOWS the N&W ran nowhere near the Canadian Pacific!" If they did, I'd suggest they have another sip of brandy and contemplate things a bit.
What's strange, however, is that I have an insatiable focus on a railroad that was started in 1855, leased and then sold to the New Haven in the 1890s, and then stopped running altogether in 1983. Most of the decorations on the walls of my train room (stock certificates, canceled checks, postcards, etc., etc., etc.) pertain to the Providence, Warren & Bristol RR which ran from Providence, RI to my town of Bristol. Thank GOD no one manufactues anything named for this road or I'd be bankrupt...

Bristol, RI
P.S. There will be a GN Empire Builder passenger set in my future due to the "nice to look at" rule.
The layouts I have done over the years have always had one idea. Model one main road but have feeder lines for interchange traffic. So over the years I have bought my engines that way. The roads have been UP, SF, MIL, NYC, D&H, CP, CN, TH&B, and South Buffalo. But I also bought some just because I liked them. SP, Reading, NP ( because I liked the passenger train colors, Nickle Plate and C&O......Paul
Yes I am. Mine. :-)
Yes, New York Central
No, but in the last few years Its been streamlined mostly. Thinking of selling most of my non-streamliners because I'am just not using them. They don't do much good just sitting.
Yes, the Lionel Lines Railway, which serves the mighty town of Plasticville. Of course, the Lionel Lines Railway has been short of motive power, so it has been leasing power and rolling stock from the Reading, Pennsy, NYC, LV, CNJ, Milwalkee Road, Southern, UP, Amtrak, and others.
American Flyer Lines also serves the town, but it doesn't have nearly the use of the Lionel Lines Railway.
I run MEC ...The Maine Central....because it's local...and nice colors...always trying to find another MEC engine and freight/pulp cars
I mostly have about 90% Pennsy
Again, No by Definition. I like the PRR as well as Modern Amtrak and Modern Conrail because those are the RR's I grew Up with. 
I can't stand all black loco rr's like early Conrail , PC and now NS.
I also like the universal and rare Demonstrator models too! BTW, My cut-off is 1998 across the board due to financial & spacial reasons!
One....and only one as questioned by the OP....would bore my silly. Fast. And be rather limiting and restrictive, at the end of the day.
Now, two to three primary railroads along with multiple "supporting" or connecting railroads is quite common, IMHO....but not just one RR.
Yes, I like:
and
Yes, I am loyal to my railroad, The Lenny Lines. However The Lenny Lines interchanges with every railroad in the world so you never know what you'll see
I would never be so limiting.
