 The Act did not specify a rate of payment, but rather left the remuneration to be agreed between the railways and the Postmaster-General, or if necessary settled by arbitration.These agreements were subject to alteration at a month's notice, though the Postmaster-General had the power to terminate the services of the railway companies without notice if compensation was paid.The penalty for refusing or neglecting to convey the mails was £20, and the railways could be required to post security by bond, under a penalty of £100 per day for neglect.
