I had drawn some earlier crossings (without the automatic gates) but these are not in r310 ... In the 1850s there are no available crossings, which makes gameplay rather annoying.
Would it be proper to draw some crossings with a "house" (signal-box?) and manual gates, like still survives at Chartham Kent? see http://www.flickr.com/photos/boxley/4438714924/
Also the HQ needs introduction dates for the new makeobj, as no HQs are available in the 1850s either.
WLindley,
hadn't noticed your post until just now: apologies. Yes, by all means do some extra graphics for the earlier crossings - the more the merrier :-)
