For those who will be reporting to Livingston Street in the immediate future, click here for the pre-employment packet (if you need it). The CPD-B booklet is not necessary since this is not a civil service position.
For those of you who are still waiting, you folks might want to check out this and this YouTube video. In addition, if you need help getting your Class B CLP (Commercial Learner's Permit), I would encourage you to check out cristcdl.com, which is free! Remember, the multiple-choice tests you need to take and pass, at minimum, are General Knowledge, Air Brakes and Passenger Endorsement.
