Political work to extend the line to Elverum started even before the opening of the southern half, and was debated in Parliament in 1893. Railways were in the wind and there were many projects competing for political support. Initially only a minority was willing to support the line. Several trunk lines were being proposed, and there was political struggling for various parliamentarians to gather support for "their" line. This resulted in the Great Railway Compromise of 1894. The Solør Line was the most popular, receiving 105 against 5 votes on 1 March. The same day four other major railway lines were passed.
