the theater. Railway groups are assigned on the basis of one per two
to six transportation railway battalions.
c. The transportation railway brigade is assigned to supervise a
very large TRS operation where three or more transportation railway
groups are required. However, the rail operation is seldom large
enough to require this level of supervision.
4.6. EXAMPLE OF DETERMINING TRS UNITS REQUIRED
Assume that you are going to operate a five division railroad
and you need 215 crews. You must determine the number of TRS units
needed to operate the rail line. The first step is to divide 215
(crews required) by 40 (crews provided daily per TRB). The normal
assignment would be five TRB's with the 15 additional crews assigned
through augmentation authorized by TOE 55520. One railway group
would be required to supervise the operation.
4.7. SUMMARY
The number of transportation railway service personnel required
to operate a military railroad in a theater of operations depends
primarily on the number of railway battalions needed. The number of
TRB's required is based on the number of road and switch crews needed
to operate the entire railroad. The amount of working time
necessitated by the particular rail operation determines the number
of traincrews required.
Forty traincrews, including both road and switch crews, can be
provided daily by the transportation railway battalion's attached
train operating company. Road crews should not work more than a 12
hour shift to allow sufficient time off for them to rest. In
emergencies, however, the 12hour shift can be exceeded for short
periods provided the time off between runs is lengthened
proportionately. Switchcrew requirements are based on the number of
switch engines in use. Two such crews are required per switch engine
per day. Both road and switchcrew requirements are calculated by
using formulas in which you find values for the unknowns and
substitute them in the formulas.
Once you know the number of road and switch crews needed to
operate the railroad, you can find the number of railway units
needed. The number of railway battalions required determines the
number of transportation railway groups needed to supervise the
operation. Transportation railway service teams organized under
