I don't know of any location of information of an explicit detailed electrical schematic of a rides controls.
Electrical components? How about...
01) Big honkin' electric motor.
02) [Contatctor for (1) XOR
02) Soft start controller for (1) XOR
02) VFD controller for (1)]
03) Air compressor (with small electric motor)
04) Sets of solenoid air valves to control brakes
05) Air pressure switches
06) Miniature proximity switches to detect brake caliper status
07) Proximity switches positioned to detect train "check in" and "check out" for block controller
08) [Proximity switches OR
09) Mechanical switches OR
0A) Optical emitter-detector pairs] to detect train presence in brake zones
0B) [Control relays OR
0B) PLC I/O chassis]
0C) PLC CPU chassis
0D) Status indicators
0E) Control panel switches
0F) Alphanumeric display panel
10) Station smoke/heat detectors
11) Station fire alarm panel and annunciator
12) Audio amplifier(s)
13) Lift hill and brake zone speaker systems
14) Station PA speakers
15) Functional lighting systems
16) Decorative lighting systems
17) Decorative lighting controller (chase controller)
18) Telephone sets
19) Telephone intercom switch
1B) Wind speed display
1F) Distribution panels (110v and 208v, perhaps 240v or 480v)
20) Bells, buzzers, lamps, other signalling devices
That should be enough to get you started... :)
If you are looking at control systems, most of those use PLCs programmed with ladder logic. Most of the time you don't care where the train is with any precision, you just care that it is in a particular area, and that it is proceeding as expected. You may care about the speed at particular points. Typically you will find proximity switches used to identify the start and end of each block, with a target on one end of the train on one side and a target on the other end of the train on the other side, so that the train checks into and then checks out of each block. That way the controller can handle the case of a train that has entered a block but not yet left the previous block.
The one place where precise train position is needed is in the station, to park the train for loading and unloading. That is frequently handled by a series of switches mounted a few inches apart which are triggered in sequence as the train approaches. That way when the first switch is triggered the brakes can be cycled, and the train inched forward until the last switch is triggered, signalling that the train has parked.

That was literally a list off the top of my head, so I figure I missed a lot of stuff... :)
