A couple recently.
First was last night. I was at York Station, which looked reasonably like the real thing. A train drew into the westernmost through platform which I understood to be a Cross-Country from Portsmouth Harbour to York, and I also understood the current Cross-Country pattern on the Reading-North East axis to involve a two-hourly Portsmouth-York service. Oddly, despite me understanding that it terminated at York, I remember noting passengers on it as it pulled out. I remember it was quite lightly-loaded but the middle part of the train was quite full. I also remember it consisted of three units, each 3 or 4 cars, and the total length was 10 or 11 coaches. These units did not resemble any real unit classes I know of, but had something of a TGV-like look about them. One unit had a red-and-silver livery and the other two blue-and-silver. The rear unit had a "nose"-like design (class 37-esque) and had a four-digit number and most bizarrely of all, there were one or two freight wagons attached to the back.
The second one, a week or two back, was set not in York, but in New York. I was coming into New York on an Inter-City of some kind from further west in the USA, and remember being disappointed that much of the journey was underground (and I recall sleeping as a result). I woke up in a tunnel purportedly coming into "New York Station" (which was neither Grand Central nor Penn, but some other station; it was a terminus) and saw a notice in the tunnel reading "NOW ENTERING EAST SIDE". Then the train came out of the tunnel and passed a park; I remember noting it was autumn, but despite it being October the trees were semi-bare and resembled November. But then, bizarrely, the train entered countryside at quite a high elevation and continued for a couple of miles across green fields with a river valley to the left perhaps 100 metres below the level of the railway. So in this alternate New York, there was an island of countryside within the urban area. Bizarrely this alternative New York geography, with an elevated area of countryside in the midst of the urban area, is a recurring dream; it's come to me before, albeit without the railway. Finally the railway arrived on a hill crest and I could see the main part of Manhattan ahead, with the Empire State Building, and sea further ahead. The top of the hill was about the same elevation above sea level as the top of the Empire State Building, so perhaps 400 metres odd.
I knew the train would be terminating at New York Station very soon but then I woke up...
There was no Hudson River in this alternate New York, but an altered geographical layout, and the train was arriving into central Manhattan from the east despite originating further west in the USA. The geography was perhaps a headland, protruding southwards and then westwards, on which New York was situated and a bay separating it and the land to the west, with the train taking a big curve along this headland to enter New York.
