HO scale Muscoot Valley RR in Great Model Railroads 2005

I have recently been going through GMR 2005 in detail, and am wondering about the coal dock on the MVRR.

From the looks of the track plan on page 98, there appears to be room for only two, maybe three cars, the locomotive and tender to be able to get on to the coal dock via the switchback.

In addition it appears that it is practical to pull coal cars from only one yard track to take up the coal dock.

Does anyone have any further information or comments?

Thank you
