Okay so this is something new I found about ROTR!! There are such times where only one ride transport is ran, and it has a completely new custom programmed track/route (sorta).
I guess this happens when something must be wrong with one of the loading platform chargers.
Anyways in the first room, you’re only faced with only one other transport (when Bek tells you to tell them that you’re just another prisoner transfer). At this point of the sequence, you are technically the second lagging ride transport in track B, if there were two transports still present.
After this room, in the hallway leading to the probe droid, the current lonely ride transport transitions to track A. It races, speeds up (really it does!) to reach the probe droid which is already down, jutting itself forward towards the probe, then backing up quickly. So basically we went from track B to A in this hallway sequence. From this point forward, the current loner transport remains in track A
Some screen grabs showing the missing transport:
Other transport that should be leading the pack is missing, versus what should happen:
Other transport missing from other elevator, elevator also doesn’t move since it’s empty.
Cannon room without transport that would be leading and going first in this room, versus what it should look like:
And last, the escape pod bay without the leading transport, versus what should happen:
I just thought this was really cool as the Imagineers thought of this situation and actually accounted for it by programming a custom track for it! I guess we can officially dub this as Track A/B since it technically does both throughout its escape.
I attached the video of this specific ride, starts @ 27:03
