1. DPU unit didn't response to Banking Comm, i should manually stick the reverser to forward on the DPU unit. 2. GEVOS sound actually pretty weird, the idle is good though, the problem is when throttling up. 3. Driver seat POV on GEVOS is too forward. 4. The dynamic brake on GEVOS is simply too strong, i hope it behave like SMH SD70ACe Dyn Brake. 5. There is no squeaking wheel vs rail sound when a train negotiate any curve/turn.
