This game is fictional. Electric railroad crossing signals weren’t in the western times. There was just crossbucks (railroad crossing signs) only.
This is one of my popular games I made in Roblox. This video shows what it used to look like in 2020, and what it looks like in 2023. You may notice some crossings with no audio, due to the audio removal update by Roblox.
Older railroad crossings in Roblox used decals for the lights and the equipment was low quality. Newer railroad crossings in Roblox today have the lights, incandescent or LED, made out of parts. The equipment is almost realistically detailed to be accurate to the ones in real life.
People were okay with the early 2020 version of my game, but in late 2020, just few months after I updated my game, some people and my former friends told me to remove those railroad crossing models, as they said they were “leaked” models. I finally did as of 2023, and they are replaced with newer and realistic models.
