I don't follow your reasoning. If the genesis of the accident is a bus swerving to miss a car, then I can't see that the tram's signalling is in any way implicated. Sorry, I didn't make myself clear. In Croydon, as is the case elsewhere with other tram systems, the highway traffic control signals are linked in to the tram's signalling system so as to enable trams to negotiate a variety of road junctions - this evidently requires a more complex set of interlinking/interoperability (or even 'interlocking' as it were) between the highway signals and the tram network's signalling system. On top of that one can assume that at least some of the highway signals in the area are co-ordinated with each other as part of a traffic management setup (as I'm sure is the case in central Croydon). *If* the highway signals (indeed and the tram signals) had malfunctioned then this could have caused or contributed towards the car and/or bus (indeed and/or tram) being in the wrong place, hence the relevance of this factor. Okay, that's clearer. Thanks. -- http://gallery120232.fotopic.net/p9632771.html (20 077 at Buxton, Jun 1985) |
