(The Elevated did train wood and steel cars together though)
The #4 cars (0220-0239) built by Pressed Steel in 1911 were consructed with anti-climbers, which were by that
time, an industry standard.
I'm guessing that the Elevated experimented with different anti-climber designs.

The anticlimber was intended to prevent telescoping, when two cars collide and one rides up into the other's body, resulting in massive casualties. Good example of the effect of anticlimbers is the 1974 collision in the Beacon Hill Tunnel. 01427, a steel car, struck o1604, an aluminum car. Without anticlimbers, the steel car would have plowed through the aluminum car. The anticlimbers transmitted the impact to the car frames, which absorbed the impact. The steel car bent upwards at the center. The end of the aluminum car accordioned, crushing the cab. Both cars were total losses, but there were (IIRC) no fatalities, and only a few major injuries.
The Elevated constantly tried new things. The six-button door controls allowed all doors in a car to be controlled from one end of the car, eliminating the need for guards between every pair of cars, and platform men at stations to unlock the center doors. Guards between every pair of cars were not completely eliminated until 1918. At that time eight car trains had been run. The six-button system was introduced in 1912 and spread through the Elevated through 1918.

The next stop is Washington. Change for Forest Hills Trains on the Winter St. Platform, and Everett Trains on the Summer St. Platform. This is an Ashmont train, change for Braintree at Columbia.
