No Zurich doesn't invest more they just prepay and ask the SBB for the money back, which is a way to force investment there. Both base tunnels were paid by whole CH but don't really benefit western Switzerland which has to use the most underfunded line between Geneva and Lausanne (2nd and 4th cities by size). If there any kind of issue on the 2 tracks the traffic between the cities is blocked. About half of the train are late, as there is way too much traffic and a single glitch everything crumble. Some works created a big hole andthe line was cut for 3 weeks. nobody in the Swiss German part gave a heck about it. If the line between Bern and Zurich (with no backup) was cut for 3 weeks it would be a national drama… If you don't believe me, just look at the stats regarding late train between Western Switzerland and the rest of the country. It's very telling.
