b. A check of the standings of the trains with figure 2.1 shows
that trains 1 and 2 are local freights between Conroy and Maxey yards
with setoffs at stations along the way. In actual practice, such
trains would also pick up cars at stations for movements to points
farther along the line. Each pickup would have to be cut into the
train with a car or block bound for the same destination or in the
correct order between blocks to insure its readiness behind the
engine for setting off at the proper point along the route.
c. Train 3 consists of four blocks of cars all bound for Maxey
yard and points beyond on the south route. It would move from Conroy
to Maxey as a through train, and on arrival at Maxey, would become
the responsibility of the yardmaster there. At Maxey, the groups may
be separated from each other for makeup into new trains, but, except
for badorder cars, the blocks would not be broken up. Additional
cars for the same destinations, however, would be added to
appropriate blocks. Maxey yard to Evers now becomes an Evers
Division operation. The yardmaster at Maxey decides, on the basis of
the number of cars currently in his yard for south route
destinations, what makeup is required for his outbound south route
train or trains. If the consist of an arriving train were such that
it could go on to the next division with little or no change, it
would require only a fresh engine and crew. More often, however, it
would be broken up and new trains formed. Remember that if Conroy
yard had ample facilities and those at Maxey were limited, the
grouping and makeup of the train at Conroy would be such as to
require only a minimum of additional yard work at Maxey. In brief,
the work is done wherever and to whatever extent crews and facilities
exist. Ordinarily, this should be as close as possible to the point
of freight origin.
d. Train 4 moves from Conroy to Maxey as a through freight. On
arrival, the Maxey yardmaster might choose simply to cut off the 8 EV
cars for inclusion in a south route train. He would keep all of the
north route blocks together and add to them whenever necessary to
conform to minimum trainsize requirements. He would also provide a
fresh crew and locomotive to move the train to Elton, the next
division terminal on the north route.
e. Train 5 is also a through freight to Maxey. When it arrives
there, it will be broken up and the blocks put into new trains for
movement to final destination. Ordinarily, a train out of Conroy
would not include blocks of cars for destinations on both the north
and south routes, but in this example because the blocks are
relatively large, it is better to keep them moving forward.
