It might take them a little longer to do the clearance test - it's a pretty slow process as they're winching the train inch-by-inch along the track. That said, I don't recall ever seeing how long one actually takes. Does anyone have any idea of a typical duration?
You're right though, hopefully once they've finished the pull-through they'll be nearly ready to test properly. As we say all the time though, there's lots of work to be done with the wiring and sensor calibration and stuff once the physical structure is done. A lot of this stuff doesn't actually manifest visibly, so progress seems to slow down.
