There are several SLRR guides that remained solid for many years unnecessarily in the regions Oculea, Calleta, Sweetbay, Columbia and Tuliptree. Even though the SLRR standards don't require guides to be solid for a long time now since train scripts use llSensor() and llSetPos() to detect and follow guides in a non-physical way that does not need collisions, most of the guides even on the street-running part of the railroad in this area are solid. Some are being switched back and forth between phantom and solid by incorrectly working switches and sensors, others are always solid because they were never set to phantom.
There are several destinations for road vehicles in this area and otherwise the roadway can be used by them, the only obstacle in the way of road vehicles is the solid guides that prevent left turns, U-turns and branch line guides completely block the way of road vehicles at certain points. There is absolutely no point of using solid SLRR guides anymore, so having them anywhere on Heterocera's railroads (Bellisseria railroads were already built with phantom guides except for a few trouble spots) but especially in railroad crossings and street-running parts is nothing but disruptive.
In detail:
The switch at http://maps.secondlife.com/secondlife/Oculea/242/32/35 works properly but the railroad crossing sensors at both ends of the crossing make the guides solid for several seconds, so if a road vehicle enters the crossing right after a train passed, it will get stuck in the still solid guides. Turning the guides solid for the passing train is pointless and unnecessary. The sensors should only activate the crossing barriers and not affect the guides.
The switch at http://maps.secondlife.com/secondlife/Calleta/248/49/33 makes all active guides solid and makes all Alternate Guides phantom consistently. It should only change the names of the guides between Guide and Alternate Guide, but they all should stay phantom all the time.
At http://maps.secondlife.com/secondlife/Columbia/65/248/33 the main line guides of the switch are phantom but the branch line guides are all solid, the switch doesn't affect this so the solid guides should simply be set to phantom.
From http://maps.secondlife.com/secondlife/Sweetbay/47/6/33 to http://maps.secondlife.com/secondlife/Columbia/76/240/33 several guides are solid except in some properly working switches.
The switch at http://maps.secondlife.com/secondlife/Columbia/89/229/33 works properly and its guides stay phantom regardless which way the switch is set, but from this point to the end of the railroad all guides are solid (except about three pieces) all the way to http://maps.secondlife.com/secondlife/Tuliptree/153/166/31 where the last guide is not only solid but named "end" instead of "Guide", so you can't pull in to the end of the platform with a locomotive here. Depending on the type of vehicle it will derail or get stuck when reaching the last, improperly named guide. The last guide should be named Guide and not "end".
It would be appreciated if you could inspect all guides, sensors and switches at and between these marked locations in this area to make sure guides will be and stay phantom at all times, and also appropriately named Guide when active and Alternate Guide when inactive in switches. Thank you in advance.
