YA Book about a girl and two friends solving cases NOT Nancy Drew

[Kenzie]

My grandpa gave me some of these books when I was younger (probably 2005 ish) but the series is older than this.
The books all follow a girl with two of her friends (i cannot remember any names). One book I specifically remember is the group accidentally ending up on s runaway train and they find a Native American who is helping them maybe get back home?
I want to say the title was possible “Lizzy and the Runaway Train” but I’ve searched that and have come up with nothing.
I don’t remember the name of the girl or her friends or the author.

Mandie and the Ghost Bandits by Lois Gladys Leppard?
It's the third book of the Mandie Series, which has a girl solving cases with her friends and often features Native American characters.

I found this but haven't found a Goodreads match. Haven't really found any other reference to it yet.

That and all others by John L WIlliams are recent. Liza Jane and the Runaway Train is from 2020. Could be privately published. No record on worldcat.org.

A quick way to confirm if it is your book, is to read/borrow free from openlibrary. Mandie and the ghost bandits.
Why suggest google books when you can read the whole book! Openlibrary is also an easier way to search keywords and read them in context once the book is borrowed.
