Which type of vehicles are more prone to getting stuck on a railroad-highway crossing?

Low Slug Units with a long trailer are more prone to getting stuck on a railroad-highway crossing due to their design and dimensions. These vehicles typically have a longer and lower profile, which may result in their undercarriage being closer to the ground. When navigating over railroad tracks, particularly if the tracks are elevated or if there are steep approaches, there is a higher risk that the vehicle could bottom out or become lodged.

Additionally, these units may struggle more with uneven surfaces often found at crossings, where depressions or misalignments can pose challenges. The long trailer aspect further compounds the issue, as it can create a larger turning radius and may make it harder to maneuver away from tracks if the vehicle begins to get stuck.

In contrast, heavy-duty trucks with double trailers and high-clearance vehicles generally have a design purpose and configurations that mitigate the risks associated with crossing railroad tracks. Standard passenger vehicles, while they can face issues at crossings, are less likely to get stuck compared to specialized units designed for cargo.
