My guess would be that they have designed the launch track to be long enough to slow down the train starting with the backwards launch so that if the switch fails to align, it will slow it down, but still have the forward launch. At least, that's how I would program it. I would also program it to not allow dispatch until the first train clears the top hat. Most likely, they will do it this way, but Park Ops will probably dictate that dispatches are not to occur until the first train enters the brake run to avoid a launch fail due to block setup. Makes sense since they are only having 2 trains. Would be a very easy ride to keep roll-ins consistent.
