You killed the immersion factor when you ditched the dispatcher and engineer voice activity for the GP40-2 scenarios in CSX:HH and GP-38-2 / GP40-2 scenarios in NEC. (Also Amtrak) You made it so lifeless. Please bring this feature back!!!
I've never heard those voices at all: just occasional static and garble from radio. Does it have to be turned on, volume turned up? If so, how? Let me recall, however, that I got really sick and tired of hearing calls for "Foreman Dan Hernandez" in TSxxxx.
