If you wish to participate in tours, and other activities over several days, you are entitled to access to convention activities with your NTS name badge. However, if you wish to participate in convention activities before the NTS registration opens on Wednesday of convention week, you must contact NMRA Headquarters and request your credentials no later than July 31, 2015. NMRA HQ has a procedure for NTS Exhibitors, allowing for two PDX 2015 name badges per registered Company. Registration packs will be at the pre-registration desk for pickup on Sunday, August 23, as with other participants. Tours and other extra-fares can then be purchased as desired. Tours cannot be purchased in advance.
