Train running from our signal box to the neighbouring signal box

Before we can send a train to the neighbouring signal box, we have to switch on the line block by pushing the "Wbl" button. The starter field indicator starts flashing white. The neighbouring traffic controller must agree to the activation. While the starter field indicator is flashing white, the request to switch on the block can be cancelled by pulling the "Wbl" button.

As soon as the neighbouring signalman has given his permission, the starter field indicator changes to steady white light and we can set our exit signal to clear.
