The town was created by Irish settlers at the beginning of the 1900's. Their current logo, also viewable in the header of their site listed above, is extremely dated, but has elements that are relevant to their history. Both the train(or possibly train tracks if it flows better) and the shamrock/s need to be incorporated in some way.
Their goal is to update the current logo to be more modern and "hip", but that does not mean it needs the same layout. Only the general idea should transfer over.
I've attached some mockups of what their website homepage redesign will look like when finished. The general design of the logo will need to look nice in the header. I've also included versions with no place-holder text for the logo for you to overlay your designs on to check for aesthetic correlation.
EDIT: Do not use a city skyline as part of the logo. The town is small, not a city.
