Modifies provisions relating to train length restrictions

SB 1744 sets a maximum train length of 8,500 feet for all trains operating on main tracks or branch lines within Missouri. It directly affects railroad companies operating in the state by requiring compliance with this length limit. The bill grants the Missouri Department of Transportation (MoDOT) authority to create rules for measuring trains, granting route-specific exemptions, and imposing penalties for violations. MoDOT’s rules must follow standard state rulemaking procedures under Chapter 536, and any rules adopted after August 2026 would be void if related constitutional provisions are invalidated.
