Loading gauge<br />

This stipulates the maximum<br />

height,length and width of a<br />

vehicle that can travel on the<br />

network.<strong>The</strong> size varies by<br />

route, primarily because of<br />

bridge and tunnel clearances.<br />

All passenger-carying<br />

vehicles are constructed to a<br />

similar height and width.<strong>The</strong><br />

primary variable is the<br />

length,at 20m or 23m.<br />

Generally, there are few<br />

restrictions on passenger<br />

vehicles but,for freight<br />

vehicles, the capability of the<br />

network in ascending order of<br />

size (as set out in the key<br />

below) is shown on the map .<br />

Full gauging analysis undertaken*<br />

* At the time of publication we are unable to give firm timescales for this analysis work to be undertaken. Note: <strong>The</strong> data shown in this table differs from that published in the 1998 NMS and is<br />

more accurate.<strong>The</strong> forecasts in this table are based upon both the maintenance and renewal expenditure and the completion of enhancement schemes set out in this NMS.<br />
