What are these Std gauge cars?

The oval windows look much like Lionel early cars as in this topic:

Hello all ...thank you for your kind words ....the standard Knobby cars of later 1910 also have the same type  vestibule construction ....the 1910 and the 18,19 &190 knobby cars ...simply have too many parts to effectively build in a production line .... lots and lots of soldering ....  following year 1911 you still have the mesh steps , still the red primer, but now the removable roofs ....mesh steps were too many parts so dump those for the single piece stamping with 3 holes , smooth vestibules ..drop the red primer use better paint   the the race is off ..  now the 18,19, & 190 can be cranked out cheaply and effectively....  hence the cars before 1912 very rare ...after 1912 common ...no castings ..just sheet metal

here are a few of the knob cars ...high knobs mid 1910 ...medium / low end of 1910

here is a link to see some knob cars being pulled by an early black primer 1912 ( early 1910) ...cars mid and late 1910 ...https://www.youtube.com/watch?v=c_-221KL1eE

FWIW, more searching and comparing, 1911 year cars  I found at least one picture of an auction site showing a similar handrail- not the same but similar style of stamping.

Google this:

"Lionel Std Ga NYC 3 Car Psgr Set: 18 Parlor, 19 Combine, 190 Observation (type 5)"

There is also a bay item 295610764543

Thanks for your reply,

After looking through an old catalog the cars appear to be the #181 combine and #182 observation. The locomotive i found that goes with it is either a #5 special or a #51

Someone spray painted them with the baggage door open on the one side.

The maroon is the original Lionel color.

Is it possible to remove this paint to reveal the original maroon? The locomotive and tender are also repainted.

Your cars are the 180 series look to be in the 1912-14 era ...

Removing over paint can be very tricky ...many of the early Lionel pieces badly  flake paint over the years ...which may have happened to your set

The cars are relatively easy to find in original condition..just takes some time .

Good luck

Cheers Carey
