As mentioned in a previous post the second bridge over the Creek and railway is too narrow for two trams passing at the same time. To regulate the traffic flow traffic lights are needed. Fortunately I came across a website for ‘Talking Electronics’. Among lot of electronic devices (several related to model railways) was a controller for up to four traffic lights. I got in contact with the gentleman behind the electronics and yesterday I picked up a set of lights for a reasonable price. Everything was already put together and ready to go. I still have some work to do before the lights can be installed at the layout, but the short video shows their working. They are Australian and the sequence is red-gren-yellow-red.
