I found a nice pic online of the prototype of the Bachmann closed street car -

The streetcar shown was made by the American Car Company, later bought by Brill, and was operated in Washington DC. The design seems to have been a relatively common one for early electric streetcars, and is clearly similar to some horse drawn cars. Here is a link to a historic photo of an Ann Arbor car https://www.aadl.org/gallery/aastreets/site3/FRAME-3_streetcar_300_2.gif.html (https://www.aadl.org/gallery/aastreets/site3/FRAME-3_streetcar_300_2.gif.html). I have seen photos of other, very similar, cars.
