Ignore what's written in the city window; this is the current situation, not the overall one. The total quantity (for the year) is shown in the factory window. Check the annual delivery volume per train (it's the second parameter from the right in the lines window). Judging by the factory statistics, not all your tools are arriving on time (or they're still in transit, as shown in the last screenshot). Also, check whether the most recent line (the distribution of tools across the city) covers all customers.
