Most US railroads are indeed private companies, however, there have been (and still are) some exceptions, such as Amtrak and Conrail.
Conrail was formed by the US Federal Government to keep rail services operating in some industrialised areas that relied on rail transportation when the private companies that had served them were in financial difficulty (i.e Penn Central, Erie Lackawanna and others), however, Conrail passed back into private ownership eventually (it is now owned as a partnership by CSX and Norfolk Southern). That happened not too long after the 'Staggers Act' (named after a US Congressman) was passed in the US under the Carter administration. The Staggers Act effectively deregulated freight services in the US, which prior to that Act, were often hamstrung by needing approval for pretty much every move they made and sorely restricted in how and what they could charge for their services. With the coming of the Staggers Act, the tracks and service which Conrail operated could be organised more competitively, which is why Conrail went back into private ownership.
Amtrak was also formed by the Federal Government in order to keep passenger rail services going in a similar fashion to why Conrail was formed to keep freight services alive, however, unlike most countries around the world, it is difficult to run a profitable passenger transport rail service and keep ticket prices acceptable in the US, so Amtrak remains effectively a nationalised industry similar to how British Rail was in the UK before that was privatised. Like how British Rail used to be, this has led to Amtrak running crappy old trains for years because of its convoluted funding options, however, in recent times that has been somewhat remedied and it is now getting some decent investment thrown at it.
All of this complexity relates to why there are several reasons you might see various locomotives and rolling stock on different railroads. Primarily it is because freight railroads in the US are regionionalised, but freight itself often has to go beyond those regional boundaries. So most freight railroads have partnership contradeals with neigbouring railroads that allow 'trackage rights' to one another's railroads. You will sometimes see freight yards where two rail companies adjoin one another, which have one set of company locos up one end and another company's locos up the other end, and they will shunt freight between the two in order to allow freight to continue its journey pulled by a different loco. However, if they were to follow that principal strictly, freight would end up being offloaded from one boxcar and loaded up into another in order to continue its journey, and of course that would mean that a lot of rolling stock was then not earning its keep properly and a lot of time and unnecessary unloading and loading was going on. Since that would be costly for all concerned, it is simply easier to come to an amicable arrangement, and that often extends to allowing locomotives to go beyond what is strictly the boundaries of its own rail network. So, for example, in the Eastern US from New York State up through New Jersey, Pennsylvania and on to the Canadian border, you will see big US railroads such as Norfolk Southern and CSX teaming up with small regional US railroads such as NYS&W and DH, as well as big foreign railroads such as Canadian Pacific. This means that a Canadian Pacific locomotive could quite feasibly end up coming down from Canada, through the CSX and NS tracks and on to NYS&W's smaller lines, as could a liveried boxcar from any of those railroads, and indeed other railroads besides. This is especially true if a locomotive is operating as a 'Thunderbird' (i.e. a loco that is kept on standby in case of a breakdown).
Another reason you may have seen mixed liveries of locomotives and freight rolling stock in the US, is because despite the Staggers Act, there are still occasions where the Federal Government gets involved in keeping railroads going in the US. Such was the case when the Delaware and Hudson Railway got into financial difficulties. After much convoluted swapping around when Conrail was being formed, the D&H was owned by Norfolk and Western, then it was made an independent, ostensibly to compete with Conrail, then it got into financial trouble again after being sold off a few more times (once for a mere 300 thousand quid despite having literally millions-worth of track and rail assets). Because of that mess, the Federal Government ended up appointing the NYS&W as a company that would run the D&H under a Government subsidy. Eventually the D&H was bought up by Canadian Pacific, but it still operates as the D&H since the US were a bit leery about a Canadian Railroad owning a US one. So, you could at various times see a Delaware and Hudson loco in company with a Conrail one, a Norfolk Western one, a Norfolk Southern one, a Guildford Rail one (another company which owned D&H at one point), an NYS&W one, or a Canadian Pacific one, and possibly all of them at the same time.
From that you can see that the US rail system is not always as privately owned as it might at first appear, nor that the various rail companies are the mortal enemies that one might imagine, but often partners in business, which is reflected in seeing them mix and match rolling stock some of the time.
