Once upon a time, the Legislature was run by Democrats. Legislators met into the wee hours of the morning. Sometimes they were obviously drunk and a bit disorderly. Sometimes if was funny. Sometimes you had to laugh to keep from crying.
Trains are a poor way to make law.
The biggest and best trains have sneaky little amendments that help out a particular business or interest group. Amendments are added in the dark of night in the final hours when legislators are preoccupied with the budget and finishing a session on time. When Republicans took over the Legislature in 1996, they promised to be different. They would stop the trains and establish new rules designed to make the process more orderly and easier to understand. Lobbyists were caught off guard.
