FIGURE 39: ZONE 2
9.2.1 Side Windows
Nine passenger side windows are installed on
each side on X3-45. They are made, single or
double-glazed, heat absorbing AS-3 glass.
Windows are mounted in painted aluminum
extrusions, which hold the glass in place from
the top rail of the coach. The extrusion also
serves as a hinge to allow the window to swing
open when needed.
The single-glazed windows are made of tinted
tempered safety glass, while the double-glazed
windows are made of tinted tempered safety
glass outside and clear tempered glass inside.
9.2.2 Emergency Exit Windows
All side windows of the X3-45 serve as
emergency exits.
Except for the top window edge, the three glass
edges are unprotected. The workers must be
extra careful when manipulating or installing
such windows.
In addition, when it becomes necessary to lay
down the unprotected edges of the glass
window, never use a steel or concrete floor as
support. It is recommended to use a wooden
support, or even better, a padded surface.
