Low Construction and Maintenance Costs

The guideway beam for Hitachi Monorail System is produced using traditional pre-stressed concrete casting techniques:

1. The track beams are manufactured at an offsite-casting yard. The completed beams are transported to the site just before the installation. The site impact is limited to the column construction. This greatly reduces the traffic flow impacts during construction.

2. The quality of the track beams can be more precisely controlled at the casting yard than at the construction site. This is also effective for cost control.
   
   In addition, the guideway structure of Hitachi Monorail System is much lighter than the wide bridge structure required by other transit systems.
   Consequently, the columns can be narrower, which is more economical and less obtrusive.

3. The majority of the guideway is concrete, which requires no routine maintenance.

• *Note: The typical track beam length is 20-25 meters. For crossings over 30 meters, a steel track beam section is used.
