Design Speed of Alignments

Is there a way to know the design speed of alignment at discrete stations using python scripts in dynamo

Here is one way.

import clr

# Add Assemblies for AutoCAD and Civil 3D APIs
clr.AddReference('acmgd')
clr.AddReference('acdbmgd')
clr.AddReference('accoremgd')
clr.AddReference('AecBaseMgd')
clr.AddReference('AecPropDataMgd')
clr.AddReference('AeccDbMgd')
clr.AddReference('AeccPressurePipesMgd')
clr.AddReference('acdbmgdbrep')
clr.AddReference('System.Windows.Forms')

# Add standard Python references
import sys
sys.path.append('C:\Program Files (x86)\IronPython 2.7\Lib')
import os
import math

# Add references to manage arrays, collections and interact with the user
from System import *
from System.IO import *
from System.Collections.Specialized import *
from System.Windows.Forms import MessageBox

# Create an alias to the Autodesk.AutoCAD.ApplicationServices.Application class
import Autodesk.AutoCAD.ApplicationServices.Application as acapp

# Import references from AutoCAD
from Autodesk.AutoCAD.Runtime import *
from Autodesk.AutoCAD.ApplicationServices import *
from Autodesk.AutoCAD.EditorInput import *
from Autodesk.AutoCAD.DatabaseServices import *
from Autodesk.AutoCAD.Geometry import *

# Import references for Civil 3D
from Autodesk.Civil.ApplicationServices import *
from Autodesk.Civil.DatabaseServices import *

# The inputs to this node will be stored as a list in the IN variables.
dyn_align = IN[0]

adoc = Application.DocumentManager.MdiActiveDocument
editor = adoc.Editor
civdoc = CivilApplication.ActiveDocument

output = []

with adoc.LockDocument():
	with adoc.Database as db:
		with db.TransactionManager.StartTransaction() as t:
			align = dyn_align.InternalDBObject
			dSpeedCol = align.DesignSpeeds
			for i in dSpeedCol:
				output.append({"Station": i.Station, "DesignSpeed": i.Value})

			t.Commit()

OUT = output
