Maybe, but I can’t believe that someone didn’t check the clearances before pushing the train up the lift. I’m an optimist at the best of times, but I’d be hard pushed to believe that they set it off up the lift hoping to find any issues, rather than expecting a clean test run.
Minor or otherwise, having a brand new train stuck at the top of a lift hill for, what, 3 days, requiring significant steelwork alterations to free it, isn’t the best look.
At best, this is an internal comms error (testing the train before the technical specifications of track and clearance had been tested or reviewed), at worst (and assuming it did get stuck and it is a clearance issue - of course, it might not be), it’s just plain negligent.
