Tornado stalling

What seemed to be a trivial issue has escalated it to a major rebuild. Tornado was stalling in reverse passing trough Rushmoor station. I had to remove the station in order to see the problem. Badly laid track there is a dip were a 4” section was fitted is so the loco was “bridging” when driven in reverse. I need to replace the whole section to be on the safe side. I will make a start when I have the necessary track and fishplates.
