My fellow coworkers in the office were great to work with. Very knowledgeable and created a fun environment.
What I wish was different
That there was more work. Towards the end of the internship program there were not many tasks to spend time on. I also wish we were paid more considering the high cost of living in DC.
Advice
Attend every event you can. It doesn't matter if you aren't interested in the "Rail Industry Banquet", this is the best way to meet new people (and there is always free food).
