Sadly neither Iron Wolf or Batman have ever had three trains on the ride course simultaneously. Iron Wolf opened with 2 trains and that's all it has ever had, Batman has run 4 different trains on its tracks in its lifetime, but that's a whole different story. The section of track that was in question is a space made available to add a trim brake if necessary, but it was never added. Many B&M's have a section of track designed to allow the addition of a Trim with minimal modifications in the future should they have to. Also, B&M advises that when trains will not be moving for long periods of time on IW that they be moved off the track and onto the storage track to prevent "flat spots" on the wheels which would make storing them on the mainline impractical. Iron Wolf and Batman have not ever had the required number of blocks to offer adequate and safe breaking distances for three trains. Hope this clears up some of the confusion!
