I believe Sand Patch Grade used to have the "ding-ding ding-ding" railroad crossing sound effect, for some reason, it is non-existent in TSW 2 on Xbox. It is silent. If this is a bug, then please fix this DTG, as it severely affects the ambient sounds and environment.
I noticed the same bug for "some" of the railroad crossings on Peninsula Corridor. A lot of them you pass by have no/muted sounds. I thought to myself, "They did the same thing to this route that they did to Sand Patch." Strange. I want that "ding-ding-ding-ding" also.
