Of course Pension advice should only be given by a qualified adviser. That said, as a Railway Pensioner myself, I would hazard a guess that you've been in the NRDC (Network Rail Definded Contribution) scheme up until now (is it still just 4% member contribution?) and you have the one and only offer (used to be a 3 month window?) of transfering into the Defined Benefit RPS65 Final Salary Scheme (Railway Pension Scheme 65 - as opposed to the aged 60 scheme [RPS60] which is now closed to new members). Alternatively I beleive you could transfer to the NR CARE scheme (Career Average Related Earnings) that offers a different long term benefit for a reduced contribution. In general terms, a Final Salary Scheme is deemed preferable for the obvious reasons (great if you can get the full 40 years service in as in theory you should get 2/3rds of your final salary!) but you pay a much higher contribution (and so does your employer) as a result. Only you can make that choice based on your own personal circumstances.
