Lettering and Inking Today's Drawing-Penn Central/Amtrak E8 4316

Here I am applying the blue ink to today's drawing, Penn Central/Amtrak E8 #4316.  It is important to trim around the areas I fill with ink with a fine-tip pen before applying ink with the brush.
Trimming around the letters and logos gives them a crisp look.  Once the locomotive has a finished coat of ink, I once again go to the edges of the lettering and logos and touch up the edges in order to make the details as crisp as possible.
