ARM ballast - how much to order?

[Bill H]

Group;
I was recently able to get some more n scale ME code 40 flex, so I am continuing to lay track on my new layout. I am at a point that I want to prepare for ballast at a later time, by getting an preemptive order in to ARM, as it sometimes takes time for delivery. I will have 155 feet of mainline track, using N scale Midwest cork for the profile. I have tried WS ballast on a proof of concept and did not like it, and have seen some other layouts using ARM and have decided to use ARM. So my question is specific to ARM only.

Obviously, I could order some now, and then order more as needed, but I would prefer to get it all at once as one never knows how the supply chain may be in the future. So the question is, how much ARM mainline ballast in their standard bags (11.5oz) should I order for 155 feet of mainline?

Thanks.

Kind regards,
Bill

My mainline is also about that length, but more than half of it is double track, so maybe 250 ft altogether.  It is also on Midwest cork.  I went through about 5 lbs of Smith & Sons stone ballast which is very similar in density to ARM (I have some of both).    I would estimate that 5 11.5 oz bags is enough for your 155 ft, but I would double it to be conservative and to have spare for future changes/repairs.

Gary:
Thanks for the input, particularly as it is based on actual experience - which I value. Your estimate seems reasonable. I will be curious if others have a significantly different estimate or?

Kind regards,
Bill
