I 'm have a old tank car that my wife had from her old train set back in the 60s .It has a dome on it I would like to use on my layout set in the late 1990s -2000s . Could it be be used on the railroad or on display in the town park . Thanks in advance
Domed tankcars (probably ICC/DOT class 103W) would have already been rare by 1990. Display, museum, storage at a plant, or MOW are the best options. There may have been some still in revenue service at the beginning of your time period.
Back in the late 1980s, early 1990s from time to time I’d see a small domed tank car on the Chicago & North Western which evidently was in company fuel service, not interchange/revenue.
In addition to the ideas ericsp mentions above, I don’t believe it is there any longer but at the municipal truck depot for the city of Rochelle IL there used to be an old tank car tank on cement blocks which I assume was for fuel storage. And I can recall seeing some small oil storage facilities that had old tank cars, again, mounted on cement blocks, sometimes painted white.
For something really unusual, many decades ago Model Railroader printed a photo (I think in the letters section) of a gas station which as a gimmick had its office basically built into the sides of an old tank car. I think they later ran more detailed photos but I cannot recall when.

That was actually a construction article for a Tankar (registered trademark) gas station. Apparently they weren’t too unusual in one area of the East, “Back when.” The station in the article just had a cutout under the dome for a concrete block office, about 8 x 12 if memory serves. The article stated that, where the lot was large enough, the building was usually built in the form of a, “T,” spreading out behind the tank car.
The article didn’t say whether gasoline was stored in the ends of the tank car or in the more usual underground tanks.
[Edit] A Google search turned up a couple of photos of pre-1950 gas stations with the brand, but none of the tank car design.

THANKS so I will use it as fuel storage on the farm scene. Here is a photo of the tank car 
I was driving through a rural area some 80 miles northwest of Houston on December 29 coming home from a Christmas trip to relatives, when I saw a tank apparently salvaged from a railcar in a field. I thought about pohotographing it but I didn’t stop and it was rainjing a little. But, yeah, they’re around.
Toledo, OH had a gas station that utilized an old single dome tank car body in its building construction. The gas station was the 20th Century Gas Company and the station was located near downtown on a bluff above the riverside PRR Olive St. yard on Summit Street. The gas staion building was a single story concrete block structure that was approximately 20’ long by 15’ wide. The tank car body sat on the roof and was sort of nestled into the end walls. If I remember correctly, the tank was painted silver or black (maybe both). The building was painted white on the upper portion and red on the lower. I doubt the tank was used for storage, but it certainly was unique. The station disappeared in the early 70’s and the property is now just a vacant lot. I have been unable to find a picture of it in the local library archives so far.

I read an article in an old model railroader about a highway department that used an old tank car set on concrete supports to store asphalt for road repairs. The article was from the early 80’s but could be plausible for your modern layout. There was also an area for storing poles of different lengths with posts between each size and a small shed.

Thanks for all the info ! I have a small area on my layout that is for the highway department so the tank car might be use their. The tank car might also work in the junk yard .
That Tank Car is so flashy in the factory painted scheme it could be part of a gas station or museum.
For a junk yard one would assume that you are going to do some aging and rusting.

Here is what I did to the tank car
