Ok fair enough. I am a simple creature with that. Operator A has 10 trains (let’s say they are class 185s). The order new trains and terminate the lease on 1st Jan 2020 on the old stock. Operator B takes on the 10 trains on 2nd January 2020 with a view of starting service in May. If operator As replacements are late - why should operator b suffer. (Unless of course TPE fully compensate them for loss of income) But looks like we are on the same page here. This whole situation with TPE was predicated 2 years ago. Based on the simple question when was the last time a new design worked out the box with any gremlins.
