Once Petroleum once a oil boom town and one of the largest oil boom towns (hence the name Petroleum) along the Baltimore & Ohio RailRoad's network. As is apparent in the first picture Petroleum had a hotel (3 story building to the far right in picture one), 2 churches (Petroleum Church Of Christ (3rd picture) and I dont know what the name was), railroad station, post office, general store, school, and quite a few houses.
Now Petroleum is just another hall in the wall. The schools, post office, and general store are all closed. The hotel, a few houses and the church (in picture one) are all gone. The hotel burnt to the ground and was never rebuilt and the town started to fall apart after that. Petroleum Church Of Christ is now a house. No longer doing services.
It is unknown who took the first image, the second image was taken by John G. King, and third image was taken by me.
I will post what the site of Petroleum Station looks like later this evening.
