*** No and No.

Given that you asked for help, and your problem is getting enough energy to the motor to make it work properly, Tony's wire comment is a strange bit of advice to reject as its absolutley valid.

You are forgetting (or don't realise) that the point motor draws a momentary 4 amps and its voltage drop under load that is the issue, not the current carrying power of the wire.

You are way undersize at 7x.2 and Tony is right, 32x.2 will let the whole of the drive voltage/energy actually get to the point motor.

Wire size is 7/0.2. It is only about 3 feet max length. I've used 7/0.2 at 12 feet long to power point motors with no issues.

that's a bit overkill for point motors, no?

*** A that final cost you should think about Cobalt plus the AD4 accessory decoders... dead reliable and low current need - plus you can also have a panel switch (single pushbutton) plus panel lights and spare switching also on cobalt for other things... as well as just about the simplest wiring possible (and light wire if fine all round as current draw is so low)
