One of the better resources I have come across to this end is the plethora of old post cards still around depicting many of these structures, some better than others.
Most of the postcards were found on EBay unless noted, other pictures, mostly the more recent ones, come from Google and/or Bing images - credit given if the source is known.
Dates are in the picture name, x means the date is approximate. If they were available, and interesting, I included the back side of the postcards. 1910a and 1910b
would be the same card, both sides.
If the picture was really, really bad, some of them have been cleaned up and/or repaired when I had the energy.
Since many of these stations are no longer around (railfans seem to prefer the term "extant", I'm not one of them! :-), this page is mostly for historical reference.
What's the difference between a station and a depot? Most people will say "nuttin", it's a matter of preference, although many will use depot for older buildings.
If you have a picture you would like to contribute, please see the bottom of the page for how to find me, credit is always given to contributing photographers.
From Wikipedia: Former train station in Califon NJ. Now used as a museum by the Califon
Historical Society. Contributing property #27 of the Califon Historic District.
Califon hosts part of a rail trail that was created out of the former Central
Railroad of New Jersey High Bridge Branch. The trail is maintained by Hunterdon
County Parks and Recreation and is called the Columbia Trail, which includes a
scenic area known as the Ken Lockwood Gorge.
Also: Merv Griffin (1925–2007), television producer, once owned a farm a few
miles outside of Califon.[107] When he created the game show Wheel of
Fortune, he gave a nod to Califon when naming the show's production
company. To this day, Califon Productions, Inc. is the copyright
holder for all episodes of Wheel of Fortune to date, although the
show is owned by Sony Pictures Television. end Wiki
From califonboro.org: With some homes and buildings in the area, Califon was basically
rural until about 1850, when several mills were established. By 1870,
it even had a hotel. The district developed along the South Branch of
the Raritan River and by 1875, Califon was a station on the High Bridge
branch of the Central Railroad of New Jersey. The rail line was
abandoned in 1976 and now serves as a Hunterdon County administered
rail trail called Columbia Trail, which runs south to High Bridge
and north to points in Morris County. end califonboro

Looks like they have two signals, but the dwarf semaphore looks like they take
in at night so people can't run off with it :-)
Someone should donate a REAL train signal for them to erect and display!....
From Wikiwand: Union is a NJ Transit railroad station in Union NJ. Located
on the Conrail Lehigh Line, Union is served by Raritan Valley Line trains that
travel between Newark Penn Station and Raritan. There is also limited service to
and from High Bridge and New York Penn Station and one morning train to Hoboken
Terminal. The physical structures of the station are owned by NJ Transit; however,
the land remains the property of Conrail Shared Assets Operations, which is in turn
owned by Norfolk Southern Railway and CSX Corporation. Because the station is on an
active freight line, both tracks passing the station have a gauntlet
track to bring the passenger trains closer to the platform than the freights.
According to Wikiwand, 30-40 freights operate past the station depending
on the day of the week. end Wiki

I wonder what happened to all of the "stuff" when they abandoned this line from Allentown PA to Warwick NY???
The depot is now owned by an engineering company.

Disclaimers:
I love trains, and I love signals. I am not an expert. My webpages reflect what I find on the topic of the page. This is something I have fun with while
trying to help others.
Please Note: Since the main focus of my two websites is railroad signals, the railfan guides are oriented towards the signal fan being able to locate them.
For those of you into the modeling aspect of our hobby, my
indexa page has a list of almost everything railroad oriented
I can think of to provide you with at least a few pictures to help you detail your pike.
If this is a railfan page, every effort has been made to make sure that the information contained on this map and in this railfan guide is correct. Once in a while,
an error may creep in :-)
My philosophy: Pictures and maps are worth a thousand words, especially for railfanning. Text descriptions only get you so far, especially if you get lost or
disoriented. Take along good maps.... a GPS is OK to get somewhere, but maps are still better if you get lost! I belong to AAA, which allows you to get
local maps for free when you visit the local branches. ADC puts out a nice series of county maps for the Washington DC area, but their state maps do not have the
railroads on them. If you can find em, I like the National Geographic map book of the U.S..... good, clear, and concise graphics, and they do a really good job
of showing you where tourist type attractions are, although they too lack the railroads. Other notes about specific areas will show up on that page if known.
Aerial shots were taken from either Google or Bing Maps as noted. Screen captures are made
with Snagit, a Techsmith product... a great tool if you have never used it!
By the way, floobydust is a term I picked up 30-40 years ago from a National Semiconductor data book, and means miscellaneous
and/or other stuff.
Pictures and additional information is always needed if anyone feels inclined to take 'em, send 'em, and share 'em, or if you have something to add or correct.... credit
is always given! Please be NICE!!! Contact info is here
