Dave The key to modifying the symbol definition may lie in the file thText.mp in the sources Ie Here is the code from 5.3.9 as an example vardef p_label@#(expr txt,pos,rot,mode) = if (mode=1) or (mode=7): interim labeloffset:=(u/8) fi; lab:=thelabel@#(txt, pos); if mode>1: pickup PenD fi; if mode=1: pickup pencircle scaled (u/6); drawdot(pos); process_label(pos,0); elseif mode=2: process_uplabel; elseif mode=3: process_downlabel; elseif mode=4: process_updownlabel; elseif mode=5: process_circledlabel; elseif mode=6: process_boxedlabel; elseif mode=7: process_label(pos,rot); % station name elseif mode=8: process_filledlabel(pos, rot); else: process_label(pos,rot); fi; enddef; I have not looked into how it works, but I'm guessing the 'point height' and 'point passage-height' labels are one of the 'modes' above, and that the processes called are default metapost routines. Too complicated for me to unravel. BTW shouldn't you be using 'point height' to indicate the height of cobble banks, rather than 'point passage-height'? (Probably the same symbol size issue will apply). Also, as a path to a possible work around, I think the AUT symbol set includes the option to label 'line pit' (or is it 'line wall:pit')? I have never managed to get it to work - but have not tried too hard either.

Vasily - I'm already using base-scale to control the size of other symbols but this one is too big. I need to make it smaller without changing all the symbols. The size is probably related to the font size but again I'm happy with the font size for labels etc, I just want to change this particular symbol.
