The last sentence in Rule 53(a) reads as follows: "Engineers in chain-gang service will run first-in, first-out and, to preserve this order, it will be permissible to run an engineer out on other than the train for which called, if practicable."

For Fifth District only, it is agreed the last sentence in Rule 53(a) is changed to read:

"Engineers in chain-gang service will remain with the train for which called regardless of their respective first-in, first-out order."

This agreement will be effective January 1, 1982 and will terminate ten days after written notice is served by either party upon the other.

Dated at Omaha, Nebraska this 29th day of December, 1981.
