The route is very large. Is there a solution to this problem, or should I split it into two routes?
Welcome here, Joe
Seems to be a memory exhaustion issue then. I suggest to split it into two segments and merge in Surveyor.
Form the memory point of view: TransDEM is a 32bit process. On 32bit Windows systems this means a maximum of 2GB virtual memory. With the tweak explained in the manual you can increase the limit to 3GB. For 64bit Windows the limit is 4GB (which is the value range of a 32bit unsigned integer). During export to Trainz TransDEM needs a lot of additional temporary storage space. Once memory allocation hits the ceiling export will abort.
