It is not uncommon for AGTs to be perceived as fully automated
unmanned operations.
It should be noted, however, that
manned AGTs also exist in Japan
and are characterized by a distinct
set of features and operational
considerations.
For example, the Yukarigaoka Line, Japan's third AGT, is a manned AGT
with a driver on board, whereas the
Port Liner and Newtram were fully
automated unmanned operation.
Japan also has other AGTs such
as the New Shuttle,
The Leo Liner,
and Astram Line
are also manned AGT system, which
are rare worldwide.
What is the rationale behind Japan
being the only country to utilize such
a manned AGT system?
The Astram Line is manned for the
purpose of guiding passengers in the
event of an emergency, given the
presence of underground sections.
In contrast, the Yukarigaoka Line,
New Shuttle, and Leo Liner have
opted not to install facilities for
unmanned operation to keep line
construction costs down.
However, these lines are equipped
with ATS/ATC as safety equipment to
ensure safety.
In the future, as it becomes
increasingly difficult to secure drivers
for the entire railroad system,
manned AGTs may gradually move
toward unmanned operation.
