Dear all,

Referring to post #3007, which handles some road side equipment for level crossings (signals and barriers) that were introduced in railML 3.3, Bane NOR are interested in an extension to this. Our technical regulations (derived from requirements from the Norwegian road authorities) require us to equip most of our road side signals with a St. Andrews cross (please refer to the cross above the signal in the attachment).

In certain cases we exclude this cross (typically on platform access level crossings or in certain cases depending on the width of the road). This is something we would like to be able to model. I would propose some kind of flag for each road signal to either opt in or out of having such a cross; such as @hasStAndrewsCross or something similar.

Best regards

Dear Terje,

thank you for bringing up this idea.
Your solution proposal is a boolean attribute, which is the smallest possible model. Therefore, I want to ask, if there are any other information related to the St. Andrews Cross that you may want to model? For example, when its location is relevant, we need more than just a boolean attribute... So, what are your requirements? Btw, this question goes to the whole railML IS community, of course :-)

Best regards
Christian

Hi

Like the Norwegian case the need of representing St. Andrews crosses also apply on the Swedish network. These normally exists at level crossings every time they are equiped with active protection like, acoustic bells, lights, barriers in different combinations. Level crossings with no active protection can also be equiped with only St.Andrew Crosses or together with "STOP" signs.

From our point of view the need is to know wether it exist or not, atleast when there is no active protection.

As it can be seen with STOP signs this can also be taken into account when modelling (possible other signs and combinations exists in different countries).

Best regards
Fredrik

Dear Christian,

In the previous railML workshop, this topic was mentioned. Specifically, whether a boolean parameter for the whole level crossing for the presence of the St. Andrew's cross would suffice. Bane NOR's engineering requirements indicates that this should be on a "per road signal basis", at least for our use case. We have cases where:

- All the road signals at a level crossing has a St. Andrew's cross.
- None of the road signals at a level crossing has a St. Andrew's cross.
- Only the road signals at the right side of the road at a level crossing has a St. Andrew's cross.

I therefore think the most versatile modelling principle would allow to set this per signal and not per level crossing.

Best regards
Terje

Dear Terje,

I created a Gitlab issue #711 for this topic.

Dear Christian,

As you presented in today´s workshop 32 (and as part of the linked Gitlab issue), there are two approaches to modelling the presence of a St. Andrew´s cross; either with a boolean attribute for the level crossing or for each individual road light.

As per my post #3917 on Monday 02.03.26 the latter approach is what would cover Bane NOR´s use case.

Best regards
Terje
