Tram/train Level Crossings
There are currently four level crossings where trams and trains cross each other: Burke Road, Glen Iris; Glenferrie Road, Kooyong; Glenhuntly Road, Glenhuntly; and Riversdale Road, Camberwell. To accommodate the differing voltages of the 600 volt tram and 1500 volt train systems each of these level crossings is fitted with an overhead square, which can isolate the section of overhead wiring above the crossing and apply the appropriate voltage. When the signal box adjacent to the crossing interlocks the gates for trains to pass through, 1500 volts is applied, while when the gates are up 600 volts is applied.
Historically many tram/train level crossings have operated in Melbourne, all but the aforementioned four have been grade separated, or the tramway or railway has been abandoned. The first were built during the cable tram systems operation, with much reluctance on behalf of the Victorian Railways. Many more were built after the emergence of electric trams in 1906, often causing disputes between tramway operators and the Victorian Railways.

Famous quotes containing the words train and/or level:
“When Western people train the mind, the focus is generally on the left hemisphere of the cortex, which is the portion of the brain that is concerned with words and numbers. We enhance the logical, bounded, linear functions of the mind. In the East, exercises of this sort are for the purpose of getting in tune with the unconscious—to get rid of boundaries, not to create them.”
—Edward T. Hall (b. 1914)
“When science, art, literature, and philosophy are simply the manifestation of personality, they are on a level where glorious and dazzling achievements are possible, which can make a man’s name live for thousands of years. But above this level, far above, separated by an abyss, is the level where the highest things are achieved. These things are essentially anonymous.”
—Simone Weil (1909–1943)
