The plans also met with great interest from the public.
Among the many writings that were written by private individuals on the project, that of Johannes Mährlen, professor of the Polytechnic University in Stuttgart is notable.
He made topographic surveys to compare different options in 1843 at his own expense.
He found was most appropriate proposal was one that included elements from Schübler's proposal of 1836: a railway station on the Seewiesen, north of the old station, and a connection to Ludwigsburg through a tunnel under Prag.
The novelty of this proposal was that the line from this station would go to Cannstatt to the west of the palace gardens.
Moreover, this line went around the Rosenstein hill, crossed the Neckar and ran on the right (northeastern) bank of the Neckar to Esslingen.
This suggestion also raised official interest, especially since King William was opposed to a railway station on the Neckar road, near the royal facilities.
This proposal also gave more direct access to Ludwigsburg and allowed further development on the Neckar road.

When Etzel and Vignoles began their work, they found Buhler designs unsuitable.
Etzel began to prepare new plans based on Mährlen's proposals and Vignoles recommended that they be accepted for execution.
Pending final approval of the plans on 12 July 1844, Etzel made just two changes: first, it should not bypass the Rosenstein, but pass under it by a tunnel directly below the castle, this would allow Cannstatt station be placed closer to the town.
Secondly, the station would not be at Seewiesen, but instead it would be established within the existing buildings in the so-called Schloßstraßenquadrat (castle streets square) (current perimeter: Bolzstraße, Friedrichstraße, Kronenstraße and Königstraße), thus enabling shorter routes to the station.
Both proposals were not without controversy because existing houses would have to be demolished and it was feared that the Rosenstein tunnel would threaten the castle.
The cramped location of the station, which left little room for expansion, was also criticized.
Etzel gained approval for his ideas with a positive opinion from the Austrian engineer Ludwig Klein and the support of King William.
