Dual motor crane circuit

I'm making a gantry crane and I need two motors, each need to be able to be reversed the motors run optimally at 1.5V and the PSU produces 24V. Is this the most efficient way? 

Above I'm trying to make an LED flasher so that when the power is on but both DPDT switches are open the led lights are constantly illuminated, but when motor 1 turns on,  the LEDS flash

Nope, that 1 ohm resistor will most likely fry. Calculate the power dissipation.. You could probably better use an external supply in this case, or maybe even a few batteries. Try searching how to regulate big voltages down to small voltages efficiently on internet. Good luck with your project! :)

You mention the voltage but nothing of ampacity. Your trying to add resistance to get a voltage drop, you dont even factor in the motors voltage drop while being tied in with those resistors. You will not be able to make a efficient controller for this without the motors real life specs. You will also need to know the battery's/psu's internal resistance. Are you using the DPDT switches in real life? You can get DP switches with a 3rd throw for the neutral position.

Check out a circuit I made for you regarding your LED situation. You can see it on my 'Page' or right here: http://everycircuit.com/circuit/6376407565336576

yes, using DPDT switches is definitely the easiest system to make to control motor direction.
