Importing a list of freight cars fails if CR (0x0d) used for end of line character

```
Create a text file listing boxcars, but use 0x0d instead of 0x0a for the end of 
line character.  

Import the file.  It fails, only loading one car.

SwitchList should handle such files as well as Windows files correctly.
