R-32,38,40,42,44,46,62,68,142,143,160??

Why did the numbering system go from R-62 to R-142 on the IRT and R-68 to R-143 on the BMT, Is there a reason they chose not to use numbers in the 70's 80's 90's 100's etc. I even remember when the R-110 came out in 1992, why the jump in the numbering system?

The other contract numbers were already being used for things like work cars, work car overhauls, etc. There is a gap of almost 15 years between the R68 and the R142, and the added time leads to more buildup of work car orders and other Revenue contracts.

I wonder if they are also using R numbers for more types of contracts than they did back in the earlier days.

For example in the period 1930-1975 the R numbers are virtually sequential and with the exception of very few skips. The period 1980-2010. During those 45 years I count approximately 35 car types and the numbers ran from R-1 through R-46.

In the 35 years since there have been only 5 car types and there has been an explosion of over 100 R-numbers. Did the MTA at some point decide to use the sequence for many more types of contracts than the sequence was originally intended or used for?

The period 1980-2010.

Delete that sentence from my post - sorry about that - I inadvertently left it in while editing.

Its intersting that no "R" number was ever assigned for the purchase of the Speno Rail Grinder or the Sperry Rail Car.

Well the Sperry is being leased to the MTA, isn't it? Of course there wouldn't be a contract number for the Sperry, because the TA never requested a contract for a car like the Sperry to be made.

Thanks - and yes I have seen it but I was just wondering if the original intended usage changed as there seems to be an explosion of R-contracts after 1980, compared to before 1980. Did similar contracts exist before 1975 only that they were not assigned R numbers back then?
