Converting iQueryable to IEnumerable

Question

What is the problem with my code below? It's not returning any items even when matching records are present in the database. If it's wrong, how can I convert my IQueryable to IEnumerable?

public IEnumerable<TimelineItem> TimeLineItems { get; set; }
public IEnumerable<TimelineItem> GetTimeLineItems(int SelectedPID)
{
    TimeLineItems = (from t in db.TimelineItems
                     where t.ProductID == SelectedPID
                     select new { t.Description, t.Title }) as IEnumerable<TimelineItem>;
    return TimeLineItems;
}

In my opinion, if you are going to use linq then embrace it, get rid of that esoteric notation :)

   public IEnumerable<TimelineItem> GetTimeLineItems(int SelectedPID)
   {
      return db.TimelineItems.Where(tl => tl.ProductID == SelectedPID)
        .Select( tl => new TimelineItem {
            Description = tl.Description,
            Title = tl.Title })
        .AsEnumerable<TimelineItem>();
   }
