View Full Version : Chicago L train designs

October 24th, 2013, 06:43 PM
Does anyone know of a source that has dimensioned drawings of the Chicago L trains and some of their infrastructure? During a recent visit to Chicago I got plenty of pictures but scaling of off the photo images is not the best way to get accurate numbers.

The view from my window

Street view

One end

Looking for:
track to track spacing,
elevation from street to top of rail (average in the loop area),
platform height above top of rail,
3rd rail offset and elevation from the adjacent rail,

Any help would be appreciated.

I know in the UK, minimum track spacing is 3.5m from centreline to centreline, and the platform height is 1300mm above the base of the track, about 1150mm above the top of the track/base of the wheel.

I'm wondering, would it be the same in Chicago?

Hi rweber95, Thanks for the numbers.

Are JackClare199's numbers applicable to the Chicago L too?
