Introduction About Neutral Sections (By: Gazz292)

A little bit of very basic info about these neutral sections in real life, this isn't implemented in SimRail yet, but some people like to drive as realistically as possible obeying all the lineside signs, and it certainly keeps you occupied looking out for these neutral section signs without RWag64's Neutral Section location info.

The railways overhead power lines in Poland are energised at around 3kV DC, thats 3 thousand volts, Direct Current (the voltage can vary from 2kV to 3.6kV and be within 'spec')

This 'low' DC voltage can not travel that far before the voltage drops too much, and the lower the voltage the higher the current that is drawn from the system, which could lead to overheating of the wires, transformers and rectifiers at the sub stations, and possibly the motors on the train.

So the overhead wires are broken up into many isolated sections fed from different power sources along the line, as the voltage can vary by upto 1.6kV on each section you need to be drawing as little power as you can as you cross a neutral section, to avoid the risk of tripping a substation out amongst other issues.

This is a very basic explanation, there's more to it but most people are not that interested... especially as in SimRail you can just ignore these neutral sections right now and not get a 'points penalty' or cause any issue to the system.

So, to comply with the neutral section signs....

You do not need to turn the main power switch / breaker off for these sections, you just need to be drawing no motor power, so simply put the power lever / wheel to zero when you see a We8a sign that applies to your track ahead:

You can apply power again when the nose of your train passes the We9a sign:

If you are driving a (single) loco hauled train, you can re-apply power when the nose of your train passes the We9b sign, which is the above sign with an 'L' on the top of it:

If you are driving an EMU, you need to wait until the nose of your trains passes the We9a sign, which is the one without the L on top.

This is placed further ahead than the We9b sign because your pantograph is further back on an EMU than on a locomotive, so it may still be in the neutral section when your cab passes the We9b sign for locomotives.

A tip to get the motor power to zero by the time you see the We8a sign is to look for the back of the We9a sign, which is for trains running on your track in the opposite direction, and will be about 100 meters 'before' your We8a sign:

The neutral section signs will sometimes be located on posts to the side of the tracks, or on the catenary masts, and in some locations you need to look harder to figure out exactly when the signs apply to your line, and not the line next to you, which may have a staggered neutral section, especially at junctions where tracks join and leave the main line.

Notes on Exception (Lower Pantograph)

Dąbrowa Górnicza Strzemieszyce track 2 and Zawiercie track 3 those 2 have neutral section with pantograph lowering.

  1. Dąbrowa Górnicza Strzemieszyce if you're a passenger service going to Czechostowa you've to pass it surely (after the platform)
  2. Zawiercie track 3 is the one you need to get to go to Łazy Ła from Zawiercie WITH CARGO(line 160)
