Service & Warranty Information

How to Get Service Under the Terms of  the Limited One-Year Warranty

When you suspect an item is defective, please check the operator's manual for standard operation and trouble-
shooting techniques that may correct the problem.  Additional information may be found on the M.T.H. Website.  
Should you still require service, follow the instructions below to obtain warranty service.

First, e-mail, write, call or fax a M.T.H. Authorized Service Center (ASC) in your area to obtain Repair 
Authorization.  You can find the list of ASCs on the M.T.H. Website, www.mth-railking.com.  Authorized 
Service Centers are required to make warranty repairs on items sold 

only

 from that store; all other repairs may-- 

or may not be done at the store's own discretion.  If you did not purchase the item directly from the ASC, you 
will need to select a National Authorized Service Center (NASC).  These centers are compensated by M.T.H. to 
perform warranty service for any customer whose repair qualifies for warranty ser vice.  A list of NASC retailers 
can be located on the M.T.H. Website or by calling 410-381-2580.  Should the warranty no longer apply, you may 
choose either an ASC or NASC retailer to service your M.T.H. Product.  A reasonable service fee will be 
charged.

CAUTION:  Make sure the product is packed in its original factory packaging including its foam and plastic 
wrapping material to prevent damage to the merchandise.  There is no need to return the entire set if only one 
of  the components is in need of  repair 

unless otherwise instructed by the Service Center

.  

The shipment must be 

prepaid and we recommend that it be insured. A cover letter including your name, address, daytime 
phone number, e-mail address (if  available), Return Authorization number (if  required by the service 
center, a copy of your sales receipt and a full description of  the problem must be included to facilitate 
the repairs.  Please include the description regardless of  whether you discussed the problem with a 
service technician when contacting the Service Center for your Return Authorization.

Please make sure you have followed the instructions carefully before returning any merchandise for service.  
Authorized M.T.H. Service Centers are independently owned and operated and are not agents or representatives 
of  M.T.H. Electric Trains.  M.T.H. assumes no responsibility, financial or otherwise, for material left in their 
possession, or work done, by privately owned M.T.H. Authorized Service Centers.
If  you need assistance at any time email MTH Service at [email protected], or call 410 381-2580.

(NASC) within one year of  the original date of  purchase. This warranty does not cover damages caused by 
improper care, handling, or use.  Transportation costs incurred by the customer are not covered under this

questions regarding the warranty may be forwarded to M.T.H. Directly.
