Odds and Evens

When setting up the numbering scheme for locomotives, this was the plan:

From	To	Type	Comment
1	99	passenger, non-revenue	Cape Ann business use
100	199	passenger, revenue
200	299	locomotive, switcher or FM	yard or pusher service
300	599	locomotive, F series	passenger service
600	799	locomotive, GP-18 series	freight service
800	899	locomotive, GP-20 and later series	freight service

Further, all powered locos would have even road numbers, and all unpowered (dummies and slugs) would have odd road numbers. This makes it easy to figure out what's going on in multiple unit consists. The ruling grade is a hefty 3% up Cascade Pass, and this requires two powered locos. The consist shown here would not qualify!
