RANDOM

The RANDOM TROLL'S RIDDLE: On a train, Smith, Jones, and Robinson are the fireman, brakeman, and engineer but not necessarily in that order. Also on the train are three businessmen who have the same names. They will be referred to as Mr. Smith, Mr. Jones, and Mr. Robinson.

Mr. Robinson lives in Detroit.
The brakeman lives exactly halfway between Chicago and Detroit.
Mr. Jones earns exactly $20,000 per year.
The brakeman's nearest neighbor, one of the passengers, earns exactly three times as much as the brakeman.
Smith beats the fireman at billiards.
The passenger whose name is the same as the brakeman's lives in Chicago.
What is the name of the engineer?
*I'll give you a BIG BUT RANDOM hint: It's not Mr.Robinson
