In addition to IAIS's normal fleet and their longer term lease units covered in the roster, the road has also hosted a number of interesting units. Some are just passing through, some are showing off a vendor's latest product, and some are short term lease units. This is a look at all the units that don't deserve an entry of its own in the roster, but were notable.

We need your help! Many of the IAIS short leases and demonstration runs escaped our notice. Thus, if you saw any, and especially if you photographed them, we could use your contributions. Just email us at iais@iaisrailfans.org
