This situation is more complicated and with no 'resident' lockkeeper to help. His control box is all shuttered up at the end of the chamber and this lock, along with many others in the Netherlands now, is operated remotely from a central office that you ring through to from the boat waiting area where it says 'hier melden'. This saves money on staff but we do miss the lockies. As can be seen, the lock looks invitingly open and the chamber is empty of boats, ready to welcome Snail in. But - the two red lights mean that the lock is closed down and non-operational. With no response from the remote operator and wishing not for the first time on our European travels that we could d-i-y, we had a coffee break.
