What does "(absolute)" indicate?

I'm thinking that the Manual should describe both:

  • boiler water level
  • boiler water glass
Absolute is the total amount of water that is contained in the boiler. So for example, for a NSWGR D57 locomotive it might have been about 3500 imp gals.

The water glass gauge fitted to the D57 was 8" and showed the water level between 2950 and 3500 imp gals.

Hence the fireman was supposed to maintain water in the boiler between these two points. Thus in this case, the water level should have been managed between approx 84 and 100% absolute (or 0 and 100% gauge).

However for some reason the current OR code seems to operate the gauge between 70 - 100% absolute.

How about this text as a new section for the Manual entitled Boiler Management:

Is this appropriate?

I am very puzzled by the indication in the HUD (and Train Driving Info window) for the Boiler Water Glass. If I have time, I will debug the code to see what it is doing.

...and IT, being incompressible...
I suppose, "it" is missing.

If you are going to quote actual values (ie 70%, etc) I would suggest that it needs to be made clear whether they are gauge or absolute values.

You could try changing the following line from:

waterGlassPercent = (WaterFraction - WaterMinLevel) / (WaterMaxLevel - WaterMinLevel);


to

waterGlassPercent = WaterGlassLevelIN / WaterGlassLengthIN;

Quote

11.4.7.4. Station Commands
... They are inserted directly after the station name in the first column.

But what may be a bit more nice-to insert them at next (second) blank column.

$nohold is actually Train command, canceling $hold for given train.
But at 11.4.7.5. Timing Commands nothing said about that, exept all three commands are similar to respective station commands.
Hence, $nohold is currently not explained atall.
Here is similar form, as missing:

Quote

$waitsignal
Can be used to override and negate a $nowaitsignal station command for the current train.

Quote

$nowaitsignal
Normally, if a train is stopped at a station and the next signal ahead is still at danger, the train will not depart. But, there are situations where this should be overruled.

Should be added something like: "(next signal)that belongs to the same node as platform marker"

I suppose, the latter two phrases of this post are worth to be added to paragraph 11.4.6 of the official Manual.

ORTSBearingType ( x ) mentions Friction, Roller and Low. It should also include "Grease" which has a higher resistance than regular friction bearings lubricated with oil. Mostly used on very old stock, but continued on some private owner goods wagons in UK into 1930s.
