The Peter Witt streetcar is an example of an American design adopted by European cities.
I featured the Peter Witt in my book Field Guide to Trains and Locomotives and Rolling Stock published by Voyageur Press in 2016. This is also available from Amazon.
Here’s an excerpt of my text:
The Peter Witt was a widely built steel-body center-door streetcar noted for its early use of the ‘pay as you enter’ system, where passengers paid fair to the motorman and eliminated need for a conductor. Exiting passengers used the center door to minimize delays during stops. The car-type was named for its designer, the Cleveland Street Railway commissioner, who originated the car arrangement about 1915 . . . The Peter Witt was adopted in Italy in the late 1920s.
I exposed these images of a venerable Peter Witt working the streets of Milan earlier this month (April 2017) using my Lumix LX7.
See yesterday’s post Milan Peter Witt at Dusk for a view of the Peter Witt’s distinctive door arrangement.
The track condition on that curve looks like a fair deterrent to rubber-tired traffic -even in Italy.
