Yeah, the modname wont show up in the elevated rail support, technically the mod doesnt change elevated rails, it just places an invisible, uninteractable power pole in the same position when an elevated rail support is placed (and removes it when the support is destroyed)
If you place two "naked" supports next to each other, you should be able to see the wire connecting them as shown here: https://i.imgur.com/5vggU2t.png
