1579	The central lock (centrallås) in Billingsfors on 7-8-2006 at 9:51 The upper part of the board contains lights that indicate the status of the circuits and railroad crossings. The middle part contain locks that block the important points and derailment blocks. If they are all in the right position, the lower levers can be used to block the yard from other trains. These types of central locks were introduced on the smaller stations (often unmanned) in the early 1940's and are a simple solution that use mostly mechanical connections inside.	07-08-2006	16-12-2013
