Re: Uintah #50 to SVRy #250 in Transition

I have no information on the thinking behind the numbering. The old steam engines were all numbered below #100, The two mechanical switch engines #100 and #101 were 100's, so maybe something this unique and large deserved a bigger number. While we are playing with the numbers we could ask why #50 was given that number instead of following the past practice of sequential numbering? Had that been followed, it would have likely been #19. The next number question is why did mikados number #19 and #20 come from Alco numbered #102 and #101 respectively which were changed soon after delivery? They are also backwards in the order of assembly #20 being one builders number digit below #19. And then why did they number the switch engines #100 and #101 instead of following the sequential pattern, which would have made them #21 and #22? Following the sequential scheme, #250 and #251 would have been #23 and #24!
