Warranty.  Yes we handle warranty on items purchased from us.  However, if you return an item that checks okay, then you may be charged a fee of $25 plus return shipping.  Please work with us to ensure the item is both in warranty period and the problem you have experienced is the item purchased.

Additional Support

There is inherently a number of options available to enhance your upgrade work when dealing with the ERR items.  The headlight(s) and backup light(s) can be upgraded to a focused warm white LED to provide a realistic beam of light.  A chuffing smoke unit can be connected to any of the command units for realistic operation!

Note, some applications require our Cherry Switch to make smoke untis work properly.  Most AC powered steamers require a tether..Yes we have them too!  Other tethers available for steam upgrades.

All items may be custom installed by Roy Trains.
