Do anybody know if there is Total Operations Processing System (TOPS) can be accessed online for free, or where I can find a website with TOPS on
Tops is a dos based application and not available on the web as it links directly into railway it networks. I have tops on my laptop but need to connect via my companies VPN for it too work
The system itself isn't even DOS; the terminal window you see is though. It originally ran on an IBM 360 mainframe (does it still I wonder) and is written in its own programming language, TOPSTRAN, which means no-one will dare (currently) to re-write it: that and just about every train related system uses TOPS data and it'd be a nightmare to change now!

wouldn't be that hard to replace, at the end of the day it's basically a database, and by modern standards a very simple database (stores only numbers, dates and text). Furthermore, the difficult bits of development like adopting a standard numbering system were done long ago & the simple integer based numbering would be relatively easy to use as the index for a new database.
TOPS, TRUST and the other mainframe-based systems run on supported hardware and perform their jobs well. Don't assume that because they are accessed via what seems like an "antiquated" user interface that they're not fit and proper systems
Unfortunately they're not fit and proper systems. When TRUST displays a train it shows the most recent amendment even when the LTP underneath is amended for a train that is STP overlaid. As a result, Christmas day 2008, VT ran a full Euston - Manchester service according to TRUST! There are always plenty of cancelled trains that are shown running which causes obvious distress to the passenger when they find they can't get to where they want in time.
It's not just TOPS here
