This might be a stupid question, but I was running my bachmann SD45 with DCC On Board on the 126 setting on my PA2 equipped layout, and It ran unusually smooth. Is this normal? The box said it only had 28 speed steps.
Yes, it's normal. The box says 28 to show that a 28 step system can run it. According to the data for the Bachmann 1 amp decoder it's 14, 27, 28 and 128 speed steps.

28 Speed steps and 128 are the same thing.

So they just say that because E-Z command is 28 speed steps?

davidmbedard CSX Robertdavidmbedard 28 Speed steps and 128 are the same thing. David B No they aren't. OK then...show me a decoder that has a 128 speed step table......... The decoder takes the 28 speed steps and divides the difference between the steps to get a smooth transition. Hence, 28 speed steps and 128 speed steps are the same thing in decoder speek. David B

First of all, if a decoder supports 28 speed step commands but not 128 speed step cmmands and you send it 128 speed step commands it will not respond.
Second, if the decoder does support 128 speeed step commands and you send it 28 speed step commands you do not have as fine of control as you do with 128 speed step commands. If you use a table, the decoder does interpolate the intermmediate values from a 28 step table, but with 28 speed step commands, you can not set the speed to one of the intermmediate values, only the table values, with 128 speed step cmomands you can set the speed to an intermmediate value.
