Very interesting... Did TPTB gamble on all (surviving) teams checking into the Penang Pit Stop within three hours of each other, or is there going to be some equalizing factor at the beginning of the next leg? Given that teams arrive in the morning (shadows upon arrival point northwest), here's the train I believe the teams took:
Butterworth to Kuala Lumpur (1000-1730, I think this train no longer runs on weekdays)
Kuala Lumpur to Singapore (2135-0810)
There's a direct, leaving three hours earlier, that gets into Singapore at 2130 the same evening. An hours-of-operation can fix things up here for a team that gets ahead, but a team that misses the 10.00am train will not be able to get into Singapore until 4.05pm the next day, 8h behind everyone else.
Is TPTB going to herd everyone onto the 10.00am without allowing anyone on the 7.00am train, and if so, how? The first ferry from Penang to Butterworth leaves at 5.30am, so that's not going to cause teams to miss the earlier train...
Edited to add: Please note that 8.10am is not indicative of when teams actually arrive in Singapore. Malaysian trains are
frequently always late, and it's not unusual for them to be running up to three hours behind.
