Document cross-check Nypvik–Sörmyra, bandel 431

The duct schedule (kanalisation), the earthing list for the overhead contact line (KL) and the signal object and cable lists compared object by object along the chainage. The signal object list lacks a whole group of axle counter points, four cabinets are placed differently and pole references are shifted in three sections.

4 construction documents (bygghandling)Bandel 431 Nypvik–Sörmyra, km 12+000 to 21+00058 signal objects and cabinets, 151 KL polesPrepared 2026-11-05

Summary

Missing object group

12 axle counter points are missing from the signal object list

Between km 14+180 and 19+640 the objektlista (rev C) lists no räknepunkter (axle counter points). The kabellista has a cable to each of the 12 points and the kanalisation has a cable pit at each. On page 8, Rp 431-04 is followed directly by Rp 431-17.

Add the points to the objektlista, or confirm that they are to be removed from the other documents.

Cabinet positions

4 of 11 cabinets are placed differently

KS 431-07 is at km 17+150 in the kanalisation and jordningslista but at 17+390 in the signal documents, 240 m apart. KS 431-04 and KS 431-09 differ by 220 and 160 m, and KS 431-06 is on the other side of the track in the kanalisation.

Agree on one position per cabinet and update the documents that deviate.

Pole numbering

Pole references are shifted in 3 sections

20 of 93 references to KL poles point one or two poles further on than the jordningslista: the kanalisation at km 13+560–15+520 (+1) and 19+210–20+180 (+2), and the objektlista at km 16+600–17+560 (+1). Outside these sections the numbers match.

Confirm which pole numbering is current and renumber the references.

The four documents along the chainage

Each band is one document, drawn against the same km axis. An object that is in the same place in every document lines up vertically; a slanted connector or a hatched gap is a difference. Zoom in to see pole numbers and which pole each object refers to. Click an object, a pole or a difference for the source rows.

    Method

    1. Every row in the four documents was read into one list of objects, keyed on the object designation (for example Rp 431-06, KS 431-07). Cable pits in the kanalisation were matched to the object in their "Avser" column.
    2. For each object type the documents where it should appear were set: cabinets in all four, signals, axle counter points and point machines in all but the jordningslista, controlled balise groups in the two signal documents.
    3. Chainage and side were compared between documents. Any difference in chainage is reported.
    4. Every pole reference in the kanalisation and objektlista was compared with the pole at that chainage in the jordningslista. Runs of references with the same offset are reported as one section.

    Assumptions and limits

    • The jordningslista is taken as the reference for pole numbers and pole chainage, since it lists every pole.
    • Side is given as left (V) or right (H) in the direction of increasing km.
    • Only the four documents were compared. Drawings, the track layout plan and the cable route plan were not part of the check, so the review does not say which document is right.
    • Cable lengths in the kabellista, for example 495 m from KS 431-07 to Rp 431-10, were not checked against the axle counter's maximum cable length. That limit comes from the supplier's documentation and should be confirmed by the signalling designer.
