What do you mean by clear different between the trains? Other speed or was it just your seat in the train, you ment? Front or back.
Seemed as if it did not quite meet your expectations, did it?
On my way home from work, I saw that test run was in progress. Had to stop and look. Three trains in a row was running and I think maybe they were installing train nr 3, late at night. Looked really nice. 4 days to go.
But the problem with the lights on the wagon three on one of the trains is not resolved. Strangely.
