here in philadelphia pa we use radio controls on the LRV to set up all the switches for the day, we must eye verify the switch before making the turn, if it isnt working then we use the switch iron.
N/A switches that are out of order electrically have a yellow sign covering the green one. They are then treated as manual switches. Manual switches, out of order electrically switches and failed switches are changed with a switch iron. Sometimes switches will be plugged to prevent streetcars from going on certain tracks. Unlike subway and other rail, streetcar operators are responsible for switches and get 3 days without pay for 'taking a switch' (wrong way). 'split switches' are different
An electric motor moves the spring knuckle to move the switch. If the operator want to go not in the direction of the arrow (straight for instance) the operator does nothing and the switch will either stay in the desired direction or reset to that direction (mainline normally). The rear antenna resets the whole switch to make it ready for the next car. Turn signals and the frog have nothing to do with the switch. The frog is the 'split' in the overhead for the pole. N/A switches can fail
I'm a TTC streetcar operator. Here's how it's done: there are two types of single point switches-electric and manual. Electric are N/A-necessity action. Green sign with N/A and white arrow on the overhead. There is a antenna loop in the road, and streetcars have a front and rear antennae. the operator has two options when approaching the loop, depending on the arrow. if the operator wants to go in the direction of the arrow, operator presses an N/A button on far left of console to activate.
One interesting note here, many streetcar systems use "single point" switches. Meaning that as in this case there's only one switch point. It forces the car around, and the rest of the wheels go where it tells it.
Before the radio control option was developed, trams/trolleys/streetcars usually powered or coasted under a contactor on the overhead, and this would set the turnout relative to whether the vehicle was powering or coasting as the trolley pole went through. In Melbourne, the convention is powering sets the turnout to the side, coasting to straight ahead.
A transponder on the streetcar sends a signal to a reciever located near the switch to either open (turn) in the desired direction or close (aligned straight ahead). This is tied into the turn signals on the streetcar so streetcar operators know to signal their turns in advance.
A small motor pulls or pushes the frog to the desired alignment.
The switch can also be manually changed with a switchhook.
Are you fucking kidding me?? You film a switch of a tram, and a car going over it, and that's like "How do they switch tracks"??? Sheesh!!!!

Toronto still uses single bladed points, most of the world tram points are now double-bladed.

All operators must run back and reset manual switches, but not working N/A switches.

The pole follows the way the car turns - the orientation of the car is enough to guide the pole in the right direction through the frog on the wire.

There must also be a corresponding switch in the overhead when using a trolley instead of a pantograph.

How do they turn?

It looks like its activated magnetically but I could be wrong...
