There are TWO situations that involve getting past the Pinkerton security guards: one is at the rear car of the train, and you eventually can slip past him when he falls asleep*(being careful not to trigger his alarm setup).
The other guard appears when Nikola Tesla is arrested. Tesla is shackled in the Coal Car and the guard won't let you see him. Go back to the baggage car and go up through the hatch in the ceiling, which lets you walk on top of the train to get to the coal car. You have to sneak in twice, but you can leave past the guard going left without any trouble.
*There is a hidden 10th car behind the Pinkerton car. When you have proved that Tesla is innocent, Mark Twain suggests that you go to the back of the train. This is the first time that you find the guard sleeping.
The Pinkerton man is keeping you out of the rear car on the train. However, after you chase Houdini across the top of the train, you can find out what Tesla has been working on. Go back to him in the coal car and he will show you a sketch of his 200V transformer. While Edison will dismiss the device as "poorly built," you can ask Mark Twain, and he will now suggest that some answers might be found in the secret 10th car of the train.
Now when you go to the Pinkerton car, the guard is sleeping next to his pet dog. You have to make it across the room by avoiding the ridiculously intricate alarm system. Climb straight up and cross to the left above it until you reach the hole. Carefully drop through and then jump past the guard to the exit at left.
go into the lugage cart and go up the hatch,Dodge obstcals the go do the next hatch to your right, you'll come to the coal car eep going to the next one to your right the talk to the conductor he will ask if you want to get off the train
give them money i guess
you distract them.
for the guy in the back wait till he falls asleep and sneek past him and for the guy in the front climb on top of the train
you can't the demo past if the island is already there but you can play the demo on new islands.
Jump! Hehe If that doesn't work try Looking on Walktroughs on youtube Hope this helps :)!
Get past the Pimberton detective while he is sleeping.
To get past the guard to see Tesla (in the coal car), go into the luggage compartment and climb on top of all the luggage to reach the hatch that leads to the top of the train. Avoid the tunnels and the mail bags and go right until you can enter the coal car. When you have freed Tesla, you can go to the rear of the train and slip past the guard there (go up, left, across the first opening, and down past the sleeping agent and his dog).
you get a life
later in the game he falls asleep so you have to get past his contraption without waking him up
You sneak past the Pimerton detective.
You get past the pinkerton guard by going to the luggage cart and look towards the roof- there is an opening! Get past the obstacles to the coal train and talk to Tesla. Open up the drawing he shows you, and circle the breifcase. Go out to search for who broke into it. Good luck!
You don't. When you have assembled the clues to the theft of the device from Tesla, and free him, Mark Twain will suggest that you go to see who is in the mysterious 11th car of the train. The guard is asleep and you can get past him by navigating the weird device he has set up to catch intruders. (Jump over the first gap, them down past the guard.)
