Current draw for two truck shay

[Mikewolf]

Where can I find the current draw for the two truck shay, so I can correctly size the decoder I am going to order.  If anyone knows it right off the top of their head they can just put it out there.

Mine runs back and forth continuously on a 3 % grade and auto reverses.  After break in it draws  about a quarter amp uphill pulling 3 log cars a water car and a caboose.  It draws a little more on start up!
