Railway Signalling In Finland
The signalling system used on the railway network in Finland comprises color-light signals and fixed signs, used together with the Automatic Train Control system ATP-VR/RHK (an EBICAB 900 system better known as JKV, fi, junakulunvalvonta). Main signals The main signal can have any of the following aspects: If a main signal doesn't protect any switches or the speed restriction on a diverging route is the same as straight route, the signal doesn't need to show the ''Proceed 35'' aspect and therefore the yellow bottom light may be absent. The two lamp version of the old system has the lights reversed, i.e. red at the top and green at the bottom. Distant signals The distant signal is located at least before the main signal. It may also be located in the same post with a ''main signal'', below it. In this combined arrangement, whenever the main signal shows a stop aspect, the distant signal doesn't show any aspect at all. A distant signal can have any of the following aspects: ...

A moveable bridge, or movable bridge, is a bridge that moves to allow passage for boats or barges. In American English, the term is synonymous with , and the latter is the common term, but drawbridge can be limited to the narrower, historical definition used in some other forms of English, in which ''drawbridge'' refers to only a specific type of moveable bridge often found in castles . An advantage of making bridges moveable is the lower cost, due to the absence of high piers and long approaches. The principal disadvantage is that the traffic on the bridge must be halted when it is opened for passage of traffic on the waterway. For seldom-used railroad bridges over busy channels, the bridge may be left open and then closed for train passages. For small bridges, bridge movement may be enabled without the need for an engine. Some bridges are operated by the users, especially those with a boat, others by a bridgeman (or bridge tender); a few are remotely controlled using video-cam ...
