A considerable part of the reduction potential offered by energy efficient
driving may be exploited by non-technological or low-tech measures. Whereas a
fleet-wide installation of sophisticated electronic advise systems meets
considerable and time-consuming barriers, the measures discussed here may help
to obtain a saving effect in short term.
Maximum speed reduction
Tests or calculations may reveal that timetable allows for cutting maximum
speed on individual parts of a service. Especially in local networks where
stopping frequency is high and punctuality in next station is easy to predict,
drivers can be instructed to cut maximum speed by a certain amount provided they
are on time.
Coasting
Time buffers may also be used to instruct drivers where to cut off traction
provided they are running on time. This can be realised either by an extra
timetable or by signs along the track etc. |
