Bad Friedrichshall
The RB services were replaced on 14 December 2014 by Stadtbahn services on line S 41 every hour between Heilbronn station forecourt, central Heilbronn, Neckarsulm, Bad Friedrichshall, Mosbach-Neckarelz (with reversal) and Mosbach (Baden). In addition, hourly Stadtbahn services run between Mosbach (Baden) and Mosbach-Neckarelz to connect with the RE3 (Mannheim–Bad Friedrichshall–Heilbronn). In Neckarsulm, there is a four-minute connection to the shortened Regionalbahn services to Stuttgart, which also reach Heilbronn Hbf faster because they do not pass through the city centre. However, this transfer is often criticised as not working because of delays, especially in the afternoon.
