/* $Id$ */
KNOWN BUGS / PROBLEMS:
bridges:
- Clearing tiles which may not have a bridge above can cause random bridge pieces to appear, which leads to crash in the long run
electrified rails:
Normal and elrail depots look the same. Use 'X' (transparent buildings)
to distinguish between them
Missing curors / icons for construction (currently using the conventional ones)
