Pick the rail subtype first. A Rail is one of two shapes — they have different fields, so we need to know which before showing the form.
- Two-leg rail — produces two transaction legs (debit + credit) per firing. Use this for transfers between two accounts (ACH, wire, internal transfer, settlement sweep).
- Single-leg rail — produces one transaction leg per firing. Use this for fees, charges, single-sided postings, or rails reconciled by a containing TransferTemplate's ExpectedNet.
